The FXR Men's Backshift R-FX 2-in-1 Jacket is a dual-layer system built for snowmobile riders and adventure touring enthusiasts who ride through changing winter conditions. The removable liner design allows you to adjust insulation based on temperature and activity level. The HydrX 35K laminate outer shell delivers 35,000mm waterproof and 25,000mm breathable protection with windproof construction. Nylon/Spandex Omni-Lite Hybrid Stretch fabric provides unrestricted movement. The dual-layer system includes 90g F.A.S.T. 3.0 insulation in the outer shell body and a removable Thermal Dry Active Liner with 175g Thermal Flex Ultra Lite fill for 265g total insulation value. The A.C.M.T. climate control system features seam-sealed lining to prevent condensation buildup. Snowproof Dry Vent System vents at chest, biceps, and side body regulate temperature, with F.A.S.T. insulation perforated at all vents and back for improved breathability. YKK Vislon Aquaguard front zipper with full inner placket and heavy-duty waterproof zippers at chest, hand, and sleeve pockets keep moisture out. Seam-sealed critical areas and PFAS-free DWR finish add weather protection. Wear both layers for winter trips, remove the liner for spring conditions, or open vents during high-output rides. Adjustable windskirt with pant attachment system, shock-cord adjustable collar, removable/adjustable hood, and hook and loop adjustable waist and cuffs with lycra inner extensions provide secure fit.
