Airy-light and newly innovative, the technically woven STITCHLESS QUILTING creates a warmth to weight ratio like none other. The absence of stitching holes prevents both wind and down leakage and the high denier fabric has durability to prevent abrasion and a Durable Water Repellent protection to assist in keeping you dry. Packing down to our smallest stuff sack yet, this jacket is the perfect active weight for any pursuit. With everything you need and nothing to hold you back, its a new generation in body insulation!
