Arc’teryx Outdoor Equipment News, Reviews, & Information

We have compiled a long list of news and information about Arc’teryx Out door gear from the past many years into this single location. Its our attempt to help make Arc’teryx mysteries a thing of the past. What do I mean about mysteries? Well like AR LT FL abbreviations Arc’teryx uses. What the heck are those and more importantly what to they mean? That’s the kind of stuff we are trying to solve for you.

Translating GORE-TEX® Names

Which GORE-TEX® is for you?

Until recently, I thought that all GORE-TEX® was created equally.  It was all the same to me.  As long as it had GORE-TEX® in it I was satisfied the product would do the job. However, this is not the case any more.  While researching the perfect ski jacket for myself I discovered that not only are there five different types of GORE-TEX®, but the technologies are all designed for a variety of specific jobs. Outdoor companies like Arc’teryx and Kokatat have been instrumental in the development of these materials and both companies applied them in their own designs to make a waterproof product for a day on the river or a day on the backcountry steeps.

Performance Shell:

One garment, many activities. Whether you’re cycling, climbing, skiing or cruising around town, you can go from one activity to another but not have to change your jacket with GORE-TEX® Performance Shell. The Performance shell provides breathable comfort and durable waterproof protection in 2 or 3 layer fabrics. The 2 layer is supple and quite while the 3 layer is for more rugged use. (Panels in Kokatat’s Rogue Dry Top are Performance shell and ProShell offering maximum breathability and waterproofness.)

Paclite Shell:

An ideal lightweight companion for trekking, cycling, running, and other sports where weight and space are critical. GORE-TEX® Paclite® Shell combines extreme breathability and durable wind- and waterproofness with minimum weight and pack volume.

Soft Shell:

Freedom feels good. GORE-TEX® Soft Shell is the ideal fabric for a snowsport specific shell. The Soft Shell is durably waterproof, windproof, and of course super breathable. The less bulky GORE-TEX® Soft prevents that boxy feel other jackets get with multiple layering pieces underneath.

Active Shell:

Garments engineered with GORE-TEX® Active Shell are built for extreme breathability and provide durable waterproof and windproof protection for optimum comfort, guaranteed. Featuring a lighter weight, streamlined 3 layer construction, this completely new class of waterproof garments delivers extreme breathability and excellent next to skin comfort. Active Shell is ideal for all weather athletes seeking durable protection and comfort during highly aerobic activities completed in a day such as trail running, mountain biking, and fast alpine ascent.

Pro Shell:

For a rough day outside GORE-TEX® PRO SHELL is the fabric outdoor professionals and serious enthusiasts trust to perform in the face of extreme weather and tough conditions. Pro Shell has a specifically designed inner lining adding durability and moisture wicking. Made with the most rugged, most breathable, durably waterproof and windproof fabrics this GORE-TEX® is used in everything from mountaineering jackets to tough expedition grade drysuits.

Arc’teryx Theta AR Jacket Review

The Theta AR Jacket is one of the classics from Arc’teryx, with good reason. Not only is the cut flattering and efficient but when paired with the Strato Jacket or any other Arc’teryx mid layer I’m ready for anything. This shell is great for cross country skiing, a hike in backcountry, or a jaunt around town. The Gore-Tex is super waterproof, breathable, and windproof. I’m 5’6” and at 130 lbs the Medium is a perfect fit. I have enough room to layer and the fit prevents the boxy feel. I have an exceptional full range of motion in it too. What really sets this, and all Arc’teryx jackets apart, though is the hood. I’ve always had problems with not being able to get hoods to fit my head right. The patented Arc’teryx hood fits my bare head, a helmet, or a toque easily, adjusting quickly and securely, it says up even in the biggest gusts. The pockets are well placed and don’t get in the way of my daypack. The bottom of the jacket comes down far enough that I have protection from wet chairs but not so far that my mobility is affected. Arc’teryx continues to impress me and provide me with exceptional products.Have questions for me?

Outdoor Retailer : Day 2 : Arc’teryx

The Arc’teryx design team has done a great job this year – a few items we’ll be bringing in ASAP (head to the bottom of this post for a glimpse of one of the best puffies we’ve seen), others we’ll see in Spring 2010.First up is the all new Theta AR. This is a great GORE-TEX Paclite jacket with a longer length that falls below the rear, it has a stow hood, pit zips and GORE-TEX Pro Shell reinforcement – a fully decked out jacket for $349. The other Paclite jacket we liked is the Beta AR – while it’s a little shorter and lacks the pit zips, it’ll retail for $250 and has some great colors in the line up.Paclite Jacket Line UpArc’teryx’ most technical jacket is the Alpha LT. It’s “storm ready”, comes in at a light weight 13oz and has received quite a bit of press as one of the top jackets in the outdoor industry. While all the colors are great, we particularly liked it in this Aztec color.Aztec colorThe Traverse Endurance line – a line made for those of us that sweat (perspire?) – had some great pieces!The Accelero jacket is impregnated with charcoal to reduce odor and the Velox comp crew is a bi-fabric shirt that has a very soft Italian knit on the torso with mesh panels on the side.Traverse Endurance LineVelox Comp CrewThe Solano jacket is made of taped GORE-TEX Windstopper, and while that means it can’t be called waterproof, lets just say that it’s 99.9% of the way there. We think this will be a great backcountry or spring skiing addition to the line”cursor: hand; width: 400px; height: 300px;” </–>src=”” alt=”Solano Jacket Line Up” border=”0″ />The Delta LT is new this year – it’s made out of micro-grid fabric and was one of our favorite of Arc’teryx’ fleece line up. Definitely look to see the men’s version of this in the store next spring. For the women, we think we’ll be going with a similar product called the Caliber.Delta LT Line UpCaliber Line UpAlso new is the Escala line up. Made of super soft fabric, this line up with be great for climbing, yoga, pilates… or just hanging out! A hoody, two lengths of pants and two different tanks will give a lot of options.Escala Line UpEscala Line Up Women'sWe also took a look at a bunch of the “lifestyle” pieces Arc’teryx offers. They look great and we’ll definitely be bringing some of these in for next spring.Lifestyle PantsLifestyle ShirtNow for the promised puffy! The Atom is one of the nicest synthetic puffies we’ve seen. It’s trim and looks like it would be great under any of the Arc’teryx hardshells, but with great colors and wind/moisture resistant shells, it’s a great outer piece too. Look for these in the store as soon as we can get our hands on them (or maybe once the temp drops lower than 100)!Atom Synthetic PuffyInside AtomKayak Shed . .

Arcteryx Beta AR Jacket Outdoor Gear review

Arcteryx Beta AR Jacket Outdoor Gear review

We just brought in a couple Arc’teryx jackets. They are amazing. And expensive. So this is part of my ongoing review finding about what we have in stock. Found this great review from

No Beta testing needed for the Arc’Teryx Beta AR Jacket. Each year it just gets better and better. This year, the Beta AR Jacket uses Gore-Tex Pro Shell in 3-layer protection. This is Gore’s toughest hard shell, created for extreme conditions when comfort is of the highest priority in bad conditions. That’s not to say it won’t be great on a mid-winter bluebird day, but you’ll be very glad you have this jacket when a storm hits and sits around for a while. It’s been down peaks and chutes enough to prove its waterproof, weatherproof durability. The Beta was built for the skier who needs less but still wants it all. Weighing in at 451g, this seam-sealed jacket has a hood roomy enough for a helmet, reinforced shoulders to handle a pack, and underarm construction that won’t lift the jacket when you keep your hands up to stay on top of the powder.




  • Gore-Tex 3L Pro (380NR on body, 480N on reinforcement)
  • Incorporates GORE Comfort Mapping Technology, to allow max breathability and functionality
  • GORE Micro Grid Backer on inside to reduce internal abrasion and snagging, enhance breathability, and decrease weight
  • Reinforced shoulders and elbows
  • Helmet compatible Drop Hood
  • Laminated quick-dry chin guard
  • Laminated die-cut Velcro cuffs
  • One-hand pull cords
  • No-lift gusseted underarms with laminated pit zippers
  • WaterTight front, pit and pocket zippers
  • Moulded Zipper Garages
  • 2 hand pockets with laminated zippers
  • One internal laminated chest pocket
  • Articulated elbows
  • Hip length, drop back hem
  • Laminated hem drawcord
  • Micro seam allowances (1.6mm/1/16”)
  • Tiny GORE seam tape (13mm/1/2”)
  • Heat transfer labels
  • Laminated high strength hanger loop
  • 15.9 oz (451g)

Thanks for the good review!

Arcteryx Epsilon AR Jacket – Outdoor Gear Review

We just brought in a couple Arc’teryx jackets. They are amazing. And expensive. So I thought I’d find a review on one of the jackets we got in. Found this one from Product Tester:
MountainZone Tester – Raz Barnea


Softshell jackets combine insulation, wind resistance, and water repellency into a package which is compact, durable, and versatile. The beauty of softshell jackets is that they do many things well, and thus can replace several more specialized items in a pack.

The Arcteryx Epsilon AR jacket Womens and Arcteryx Epsilon AR jacket Mens is a perfect example of why softshells have become so popular of late. Weighing in at just under a pound (14 oz), this jacket is a carefully constructed feature-laden choice for aerobic activities in moderate climates with unpredictable and dynamic weather. Features like the high collar, stretch wrist gussets, multiple pockets, and great colors add to the appeal of this jacket.

The fit and feel of both the Arcteryx Epsilon AR jacket Womens and Arcteryx Epsilon AR jacket Mens is impressive. The jacket is cut to allow for maximum mobility and flexibility. The gusseted wrists keep the sleeves comfortably above the wrists, and the broad cut in the shoulders allow for great freedom of movement. The low cut in the back of the jacket did a superb job of minimizing biking “asscrackery” even while mashing up Washington’s steepest singletrack climbs.

Field testing this jacket put water repellency and wind resistance to the test. This jacket was used as an outer layer for bicycle commutes requiring high aerobic effort and wicked precipitation beautifully. Likewise this jacket was worn during several days spent sailing in moderate wind, rain, and even some hail in Puget Sound. The wind resistancy is impressive. Water repellency is good too, shedding most precipitation and soaking through only during significant downpours or after extended exposure, and then drying quickly. The jacket seems best suited to temperatures above 50 degrees or so, although the addition of thermal layers underneath would make this jacket a perfect choice for aerobically demanding activity on much colder days.


  • Excellent wind resistance.
  • Very good water repellency.
  • Compact, lightweight fabric.
  • Versatile for different activities in different climates.
  • Arcteryx Quality


  • Not as insulating as some other softshells.


My first very first softshell I acquired in November of 2005 and I pretty much lived in it for the next 22 months, but frequently found it too warm and too bulky, especially if I knew a good workout was imminent. This jacket picks up where the other leaves off, providing a great option throughout all seasons. First frost has yet to come to Seattle this season, but I am confident that with a thermal layer (or two) underneath, this jacket will perform like a champ all winter long.

Thanks for the review Raz Barnea from Had to give them props for poaching their great review of both the Arcteryx Epsilon AR jacket Womens and Arcteryx Epsilon AR jacket Mens.

Epsilon SV Jacket Review

More reviews from great sources on what we have at the kayakshed. This one is from and Craig Canapari ( DrFierce )
Epsilon impressions on 02/08/2006
I have not yet used the Epsilon SV Jacket extensively so I cannot comment on its performance. Compared to the ready mix, it has a slender, more tailored fit than the Ready Mix and the cuffs are quite preferable. Although not adjustable, they are snug without being tight (and moreover, have somewhat of a cool “ninja” aesthetic) and have an offset edge making the sleeve shorter on the palm vs. the wrist side, allowing for more dexterity while protecting your wrist. The front zipper does not have any sort of flap behind it so I worry that it may also rain to pass. The hood is comparable to the Ready Mix (from Patagonia) but slightly less structured; there are pulls for it both at the hood’s edges and inside the large front pockets, which are backed by mesh and would allow venting if necessary. Disappointingly, there are no interior or exterior chest pockets; there is a small L sleeve pocket which barely fits a 4G ipod. Most of the jacket is lined by what appears to be a fine microfiber.

Thanks this one comes from DAVID at

I have to admit that I haven’t done anything out of the everyday with the Epsilon SV jacket yet. It’s pretty much been just a daily wear piece. But it’s great so far. The Epsilon SV jacket feels almost non-existant when you wear it, it’s so light and comfortable. The fit is amazing, especially being a smaller guy, and the movement is beyond comparison with regards to other jackets I’ve worn. The Epsilon SV jacket seems to stand up pretty well to the rain and wind I’ve worn it in as well, keeping me pletty dry and warm. And the hood is a must on this jacket. It gives a better overall look and the practicality of a hood. I’m really looking forward to trying this jacket out in some more active situations. The only thing I don’t like about this jacket, and it’s not a major thing, is the brown liner they used for the interior of the jacket. Having ordered the jacket in black, the interior brown liner clashes with the exterior color, which is really only noticeable with the hood down. Other than that, if you’re looking for a comfortable, well-made, practical, and attractive jacket the Epsilon SV jacket is the jacket for you.

Sidewinder AR Jacket Review

Again in an attempt to help you know more about the gear we have this winter at the We’re finding the most informative reviews for you. This one we found this review from the folks at

Ya-Bing Chu – 2007-03-04

Minimalist excellence could use a few touches. I bought this Sidewinder AR Jacket after considering the Sidewinder SV, which has gotten a huge amount of recommendations from the community. Overall, the materials and construction of this jacket are the best I’ve ever seen. The jacket is not really insulated, which makes layering a necessity. I do wish that the jacket were a little bit longer (1-2″), I think the powder skirt would be more effective if that were the case. As it is, it is placed a little high to have much elastic strength around the right spot on the waist/hips. I also wouldn’t mind one more pocket to make it easier to stow gear for the lunch lodge. That being said, this jacket and Arcteryx will be my preferred brand for the foreseeable future.

A Great Ski Shell

Posted by Ahoff :

Arc’teryx Sidewinder AR Jacket is a great winter ski shell. It is unbelievably windproof and waterproof yet very light. The pockets are well placed and easily accessible and the overall functionality of the jacket is high. My only gripe is the hood, which when worn is good, when folded it makes a large lump on the neck that sometimes can be a nuisance. Overall I love the Sidewinder AR Jacket.

Theta SL Jacket Review

Reviewed January 24, 2005 by Kyle Larsson

Theta SL Jacket reviewed at
Thanks Trailspace for the review!

Fabric: 2.5 layer Gore Paclite with XCR reinforcements
Price Paid: $325

I bought the Theta SL Jacket for one reason, lightweight DURABLE protection form the elements, and it simply delivers. It has become the standard by which I measure all my other gear. It was the lightest 3ply GTX shell I could find when I bought it one year ago, and so far it has performed up to my expectations.
The construction, as usual for Arc’Teryx is perfect, seriously perfect, and the design of the Theta SL Jacket is darn near perfect. Arc’Teryx has the best hood design I have ever worn. The only way it could be better would be to make it from stretch fabric, and add just a little bit of elastic at the cuffs. That is the only reason it gets four stars, and really that should be like a 4.8, but not 5, it’s not that perfect.

Arc’teryx Mens Alpha SV Bib Review

Here’s another review on the Arc’teryx Mens Alpha SV Bib I found this one at
Reviewed by: Matthew Baker , Mountaineer Review Date

Price Paid: $350.00 at Second Hand
Summary: I purchased the Arc’teryx Mens Alpha SV Bib primarily for skiing and mountaineering. The fit is exceptional, and they are very durable. At first I was a little worried about the 3/4 lentgh zippers, however, this makes them much more comfortable while wearing a climbing harness. The only minor gripe is that the straps don’t have buckles, so when you want to take them off you’re forced to take your jacket off. A little pricey maybe ($600ish cnd.) but you get what you pay for. Made in Vancouver British Columbia too!

Arc’teryx Mens Alpha SV Bib  are by far the best technical waterproof bibs out there. The extra layer of tough material on the back of the calves resists stabs from my crampons, and the through the crotch zip is handy when it’s too cold to take the jacket off. As with all Arc’Teryx products, the attention to detail is apparent…waterproof zips, comfy shoulder straps, and built-in “gaiters” that cinch around your boots. I use these for ice climbing and winter mountaineering, and they stand up to the test.

Alpha SV Bib Review

Alpha SV Bib Review:
The following is a review form on the Arc’teryx SV bib. This is in an ongoing effort to give you reviews from someone else on what we have in our store. Please enjoy … and thanks to Shannon from Trailspace.

Fabric: 3-ply Gore-Tex
Price Paid: $385
The Alpha SV Bib is the perfect compliment to the jacket. Lightweight waterproof and durable. This bib has waterproof zippers that run the length of the legs, and have two-way zippers that allow for venting or removal in a flash. Arc’Teryx has placed a durable laminate material at the cuff of the inside pant to reduce crampon damage, and they also placed draw strings at the ankle for makeshift gaiters. There is a midriff drawstring to shape the fit. There is an internal pocket for sunscreen/power bar and two outer pockets for your hands. But these pockets have the same strange placement and shape as the jacket which forces the user to cross their arms to effectively cover their hands.The Alpha SV Bib is the only pant in the Arc’Teryx outerwear line that has a zipper to answer nature’s call. When you are climbing high, and you gotta go, it prevents removal of all your gear to take the suspenders off which may reduce the frostbite victims reported in 1999. The pricing is right where Mountain Hardwear and Marmot tend to be, and this bib delivers what it promises: Weatherproof, lightweight protection. A tip on sizing, if you don’t have toothpicks for legs, order one size bigger than you might normally wear. I purchased the large Alpha SV Bib and barley had room for long underwear, in between the bib. The XL was an inch longer in the leg, but there was more leg room for additional layers when Mother Nature required it.
