The FXR Child Excursion FX Bib Pants are built for warmth, weather protection, and rugged winter use on the ice. A durable 300D polyester outer shell combines with a HydrX 5K™ waterproof / 5K breathable / windproof laminate, while tough 600D polyester reinforces the seat, knees, instep, and hem in high-wear areas. F.A.S.T. 3.0™ provides a 210g combined F.A.S.T.™ / FXR Thermal Flex™ insulation value for cold-weather warmth and floatation assistance, while a moisture-wicking quick-dry mesh lining helps manage comfort. Thermal seat, dry seat, and dry knee inserts add protection in key areas, while pre-curved padded knees support mobility. Adjustable suspenders, an elasticized back waist, boot storm cuffs, and zip-off leg extensions help provide a comfortable grow-with-them fit. Large magnetic cargo pockets and a zippered chest pocket keep essentials close at hand.
