The FXR Men's Evolution F.A.S.T. Insulated Monosuit is built for long days on the ice with dependable warmth, weather protection, and integrated safety-focused features. A durable 300D polyester outer shell with abrasion-resistant 660D nylon at the knees and hem combines with a HydrX 5K™ waterproof / 5K breathable / windproof laminate and PFAS-free DWR finish. F.A.S.T. 3.0™ provides a 120g combined F.A.S.T.™ / FXR Thermal Flex™ insulation value for warmth and floatation assistance, with perforation at the vents, upper back, and seat panel to improve breathability. The Dry Vent™ System adds snowproof and moisture-resistant chest and side-body venting, while thermal seat, dry seat, and dry knee inserts increase comfort in key areas. Large cargo pockets, a tether retention D-ring with line-cutter, adjustable suspenders, padded pre-curved knees, and reflective inserts round out the ice-ready design.
