    Polartec® Power Stretch®

    Polartec® Power Stretch®

    Two-way stretch fabric that is very warm, breathable and comfortable against the skin. Ensures warmth without weight and wicks perspiration outward and away from the body.

    ONE GOAL: KEEP YOUR FEET WARM

    We set out to create our warmest bootie ever, which meant rethinking how booties are made. For the windproofing we went with GORE-TEX INFINIUM™ WINDSTOPPER® fleece-backed fabric, which also lets more moisture escape than any other windproof fabric. Then we added a second fleece layer with Polartec® Power Stretch® Pro™, which is unrivaled in overall loft. The two layers are thick enough that we had to do a "wheel well" single-layer construction by the ball of the foot to prevent the fabric from rubbing on the crank. We made the bootie high for extra warmth and gave reasonable splash protection. We recommend our Venti Soft Sock for maximum warmth.
