Per Aether: As a stand-alone piece or an insulating layer, the Boundary was designed to keep your core warm while making sure the rest of you doesn’t overheat. Containing 60 grams of PrimaLoft GOLD insulation, the jacket offers exceptional heat retention without the bulk of down, and is constructed from a silky-soft Japanese nylon with Polartec Windbloc stretch panels along the sides and underarms. These panels are highly breathable and have been strategically placed to work underneath jackets with pit zip vents, so you can get the ventilation you need, while keeping your core warm. The collar is fleece lined with a zipper garage to prevent a cold zipper from pressing against your neck. It also features zippered hand-warmer pockets and an interior zippered pocket with an audio-cord valve. Designed for active performance, the Boundary is prepared to take you to your outer limits.
