Updated with a new Omni-Lite Hybrid Stretch™ shell, the FXR Men’s Hydrogen Bib Pants combine flexible mobility, lightweight warmth, and dependable winter protection. The Nylon/Spandex Omni-Lite Hybrid Stretch™ outer shell uses a HydrX 10K™ waterproof, 8K breathable, and windproof laminate with critical seam sealing and a PFAS-free DWR finish to help block snow, moisture, and cold air. Tough 500D Oxford Nylon reinforces the knees, insteps, and hems, while 120g FXR Thermal Flex™ fill and a quilted nylon taffeta lining deliver a maximum warmth rating of 4. 

The Dry Vent™ chest pocket vent helps release excess heat while resisting snow and moisture. Padded knees and thermal, dry seat, and dry knee inserts add protection and comfort in high-contact areas, while adjustable suspenders and waist controls help dial in the fit. Heavy-duty waterproof front, chest, and hand pocket zippers add weather protection, and storm cuffs with front and rear boot-lace retention help keep the lower legs securely positioned. Reflective inserts improve visibility in low-light conditions.
