Warm, compressible and incredibly lightweight, the Transcendent Vest™ is built to keep you comfortably insulated when the temperature drops, then stuff away into a corner of your pack when not needed. The vest"s high quality 650 down fill insulation keeps you cozy during cross-country rambles or when you"re huddled at camp, yet stows neatly for uphill slogs. For multi-day treks, it packs down so small you"ll have a hard time not finding space to bring it along.
