Warm 5K snow bibs with F.A.S.T. 3.0™ flotation, reinforced panels, padded knees, and reflective visibility.

Delivering dependable winter performance at an approachable price, the FXR Men’s Fuel FX Bib Pants combine warmth, weather protection, and practical trail features. The durable 450D polyester outer shell uses a HydrX 5K™ waterproof, 5K breathable, and windproof laminate with critical seam sealing and a PFAS-free DWR finish to help block snow, moisture, and cold air. Tough 600D polyester reinforces the insteps and hems, while F.A.S.T. 3.0™ and FXR Thermal Flex™ insulation deliver a combined 225g insulation value, a maximum warmth rating of 8, and added flotation assistance. 

Perforated F.A.S.T.™ insulation at the seat panel works with the moisture-wicking quick-dry mesh lining to improve breathability during active riding. Padded knees and thermal, dry seat, and dry knee inserts add protection and comfort in key contact areas, while adjustable suspenders and an elastic back waist help maintain a secure fit. Storm cuffs, front boot-lace retention snaps, lower-leg zipper plackets, and reflective inserts round out the cold-weather design.
