The FXR Men's Boost FX 2-in-1 Jacket adapts to changing conditions with a removable thermal liner that transforms one jacket into two distinct layers. The HydrX Pro laminate shell blocks moisture with 10,000mm water resistance while maintaining 8,000g/m² breathability, keeping you dry from both external weather and internal perspiration during high-output riding.

The 450D polyester shell integrates F.A.S.T. 3.0 insulation with 90g of warmth in strategic zones, while perforated insulation at vents works with the FXR Dry Vent system to dump excess heat through chest and side openings. The removable liner adds 175g of Thermal Flex insulation for deep cold, and quick-dry mesh lining throughout wicks moisture away from your body. YKK AquaGuard zippers seal out snow and wind, while adjustable cuffs with lycra extensions, a customizable windskirt, and shock-cord collar and hem adjustments let you fine-tune protection on the fly.

Built for riders who push into backcountry terrain or log long trail miles in unpredictable weather, this jacket handles temperature swings without requiring a complete gear change. The 360-degree 3M Scotchlite reflective elements maintain visibility during early morning departures or late afternoon returns.
