The Mens Patagonia Nano Puff Vest takes the sleeves off of the classic Nano Puff jacket to bring you a warm layer in cold conditions or a wind protection layer during high-output activities. Filled with low-bulk, hydrophobic, and highly compressible PrimaLoft Gold, the Nano Puff provides exceptional warmth, even when it's wet. Encasing this great insulation is an ultralight recycled polyester shell that stops the wind and sheds moisture. The fit of the Nano Puff Vest has been improved with better shaping through the torso and waist. This Patagonia vest packs down to practically nothing and stuffs into an internal zippered chest pocket that has a carabiner clip-in loop. Two pockets zip close to secure small essentials and to warm your hands against the cold. A drawcord hem lets you cinch down the Nano Puff to seal out wind and seal in warmth. The Mens Patagonia Nano Puff Vest is lightweight and hardcore insulation for your core. Available at Travel Country Outfitters.
