Product Info

Stay warm and dry in cold conditions with the Patagonia Capilene 4 Expedition Weight One-Piece Suit. This one-piece suit is perfect for ice climbers, alpinists and skiers who need a baselayer that they don't take off until all the fun and action ends. This one-piece eliminates the extra seams and potential cold spots of traditional layering systems. Made from the warmest, most breathable baselayer in the Capilene® family, this suit has a soft, stretch feel and a smooth face that glides beneath layers. It wicks moisture and rests smoothly against your skin for increased comfort. A fully functional fly and side-zip drop-bottom ensures that you'll be ready when nature calls. So hit the mountain this season with the One-Piece Suit, your only regret will be that you didn't get it sooner.
