The shell is a mix of heavy duty 410 denier pack cloth in high-wear areas and 70 denier taffeta where more flexibility is needed. The laminate is our proprietary 3 layer WhiteOut™ waterproof breathable barrier specifically designed to handle the hellacious conditions created by active, sweaty conditions found inside a drysuit. The suit has latex booties instead of fabric socks because they are more durable, easy to replace and you can patch them in the field with Aqua Seal. Both the front main zip and relief zip are our standard flexible T-Zip zippers. Every single seam is designed for ease of taping, and every cross-seam is hot pressed.
The Arch Rival suit is also a front-entry suit (the main zipper goes across the front chest). Typically, this sort of design allows for lots of water to pour into the boat under the skirt tunnel, but we remedied this by attaching a smaller semi waterproof YKK zip the length of the outer zipper flap. This makes the outer tunnel of the drysuit almost as dry as a outer tunnel on a dry top, and also allows you to get the zipper flap to lay flat without the bumps and creases found with velcro flap seals.
