FXR Boost FX Pant

Wild forecast? Good. The FXR Men’s Boost FX Pants combine lightweight trail performance with adaptable protection for weaving through trees and crossing open terrain. The durable 450D polyester outer shell features abrasion-resistant 660D nylon at the insteps and hems, while the HydrX 10K™ waterproof, 8K breathable, and windproof laminate helps shut out snow, moisture, and cold air. Critical seam sealing and a PFAS-free DWR finish provide additional protection through changing winter conditions. 

F.A.S.T. 3.0™ technology combines with FXR Thermal Flex™ insulation for a 180g insulation value, maximum warmth rating of 7, and added flotation assistance. Perforated insulation, moisture-wicking quick-dry mesh, and snowproof Dry Vent™ thigh-pocket vents help manage heat and moisture during active riding. Thermal and dry inserts protect key seating and knee areas, while pre-curved padded knees, storm cuffs, boot-lace retention, adjustable suspenders, and a customizable waist complete the trail-ready design. Pair them with the Boost FX 2-in-1 Jacket for coordinated winter performance.
