Built for deep-freeze days from first flag to last light, the FXR Men’s Svalbard F.A.S.T. Insulated Monosuit combines maximum warmth, ice-ready safety, and heavy-duty winter protection. Its 450D polyester 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. Abrasion-resistant 660D nylon reinforces the knees, insteps, and hems, while F.A.S.T. 3.0™ and Thermal Flex™ insulation deliver a combined 290g insulation value, a maximum warmth rating of 10, and added flotation assistance around ice and open water.

Perforated F.A.S.T.™ insulation at the vents, upper back, and seat works with the moisture-wicking quick-dry mesh lining and Dry Vent™ chest and side-body system to help release excess heat during active ice fishing. Waist-height two-way leg zippers provide another way to manage airflow and make entry easier, while pre-curved padded knees and thermal and dry seat and knee inserts add protection in high-contact areas. Adjustable suspenders with a waist belt, storm cuffs, boot-lace retention, reflective inserts, and an adjustable hood with removable faux fur complete the extreme-cold design.
