Insulated 35K trail pants with ACMT™ climate control, Omni-Stretch™ mobility, Dry Vent™ airflow, and padded knees.
Built for high-performance trail riding in demanding winter conditions, the FXR Men’s Helium X Pants combine premium weather protection, flexible mobility, and lightweight insulation. The M-Series Omni-Stretch™ 450D polyester outer shell uses a HydrX 35K™ waterproof, 25K breathable, and windproof laminate with critical seam sealing and a PFAS-free DWR finish to help block snow, moisture, and cold air. Abrasion-resistant 660D nylon reinforces the insteps and hems, while 120g Thermal Flex™ Ultra Lite fill delivers a maximum warmth rating of 5 without excessive bulk.
The ACMT™ dual-layer climate control and anti-condensation system works with a seam-sealed lining and integrated venting to help manage interior heat and moisture. Dry Vent™ thigh pocket vents provide snowproof, moisture-resistant airflow, while heavy-duty waterproof zippers protect key openings. Padded knees, thermal and dry seat and knee inserts, storm cuffs, and front and rear boot-lace retention add protection in high-contact areas. Adjustable removable suspenders, waist adjustment, windskirt attachment loops, back leg-length adjusters, and reflective details complete the trail-ready design.
