Premium women’s 35K trail jacket with F.A.S.T. 4.0™ flotation, ACMT™ climate control, and adaptable warmth.

Built for peak trail performance in extreme winter conditions, the FXR Women’s Adrenaline Jacket combines maximum warmth, premium weather protection, and advanced climate control. Its Omni-Stretch™ nylon and spandex outer shell uses a HydrX 35K™ waterproof, 25K breathable, and windproof laminate with a PFAS-free DWR finish to help block snow, moisture, and cold air while maintaining flexible mobility. F.A.S.T. 4.0™ insulation adds 150g of warmth and flotation assistance through the outer shell body, while the removable Thermal Dry™ Active Liner adds 120g Thermal Flex™ fill for a total insulation value of 270g. 

With the liner installed, the Adrenaline reaches a maximum warmth rating of 10, while removing it reduces insulation to a minimum warmth rating of 4 for changing temperatures and activity levels. The ACMT™ dual-layer climate control and anti-condensation system works with integrated venting, perforated F.A.S.T.™ insulation, and the Dry Vent™ System to help manage interior heat and moisture. A YKK® VISLON® AquaGuard® front zipper, waterproof chest and vent zippers, cold-stop magnetic placket, adjustable windskirt, Lycra inner cuff extensions, and reflective inserts complete the premium cold-weather design.
