Premium 35K 2-in-1 trail jacket with F.A.S.T. 4.0™ flotation, ACMT™ climate control, and adaptable warmth.

Designed as FXR’s flagship cold-weather trail jacket, the Men’s Adrenaline FX 2-in-1 Jacket combines extreme warmth, premium materials, and advanced climate control for long days in demanding winter conditions. Its Omni-Stretch™ nylon and spandex outer shell delivers flexible mobility, while the HydrX 35K™ waterproof, 25K breathable, and windproof laminate with a PFAS-free DWR finish provides serious protection against snow, moisture, and wind. 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 FX 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 manage heat and moisture during active riding. Waterproof zippers, a cold-stop magnetic front placket, adjustable windskirt, Lycra inner cuff extensions, and reflective inserts add protection and functionality throughout the jacket.
