No cold-weather cycling gear collection is complete without a pair of wind-stopping, padded undershorts. Okay, so maybe they're a bit of a luxury item, but the Gore Bike Wear WS Women's Base Layer Shorts show that a little luxury can go a long way. After all, there's no reason your winter bike commute should be a miserable, chilling expedition.There are really two ways the WS Women's Base Layer Shorts help keep you warm and comfortable when worn under shorts or pants during cool rides. The first is moisture management. Your body has a much more difficult time regulating its temperature when your skin is wet. The push-pull effect of the polypropylene fabric draws moisture away from your body, keeping you dry. The second way the WS Women's Base Layer Shorts keep you warm is protection from the weather. Gore uses WindStopper fabric to block out wind and help your body maintain its temperature. The Contest Lady seat pad is elastic, so it moves with you, and it's designed to provide comfort over short to medium routes. Variable-density padding provides more cushioning where you need it the most. The elastic waistband is brushed on the inside for comfort. The 9% elastane in these shorts makes them stretchy, but not overly compressive. Flat-locked seams minimize abrasion, and the back is cut high so that the base layer shorts don't slip below your outer pants or shorts. The Gore Bike Wear WS Women's Base Layer Shorts come in sizes X-Small through XX-Large. They're available in Black or White.
