The foundational layer for the cold, challenging conditions of winter, refined with increased throat coverage, more protection in critical areas, and increased breathability. The updated insulation pattern on the Winter Skin Layer mimics the protection of our winter jackets: a tighter weave on the front panel increases insulation on the area most exposed to windchill while a more open weave on the back panel promotes breathability and modulates heat in less exposed areas. The updated textile also provides increased antimicrobial properties with permanent odorControl. Warmer than the Spring Fall version, the ultrabreathable, ultrasoft winter textile incorporates carbon fiber to provide permanent odorControl properties. A second-skin fit keeps the textile against your body, maximizing thermoregulating properties and push-pull moisture management for a warm, dry microclimate. Single-piece construction eliminates seams and friction. odorControl: The carbon-infused textile provides permanen...
