Grundens Ice Raider Bib

Ice fishing happens on your knees. You kneel at the hole to clear slush, drop to set a tip-up, drag the sled across a frozen Midwest lake where the wind runs flat with nothing to stop it. The Ice Raider Bib is built for that ground game: a float-assist, waterproof, insulated extreme-cold system for anglers who refuse to pack it in when the bite turns on.

We started with the same commercial-grade 2.5-layer shell as the jacket, waterproof, windproof, and fully seam sealed, the construction that has kept commercial fishermen working through the worst weather on earth. The 25K/15K waterproof and breathable rating handles the long sit and the wet kneel without soaking through, and it's made without PFAS. Slush off the auger and a wet day on the ice stay on the outside where they belong.

Inside, body-mapped G-Loft Eco Plus insulation regulates heat where you need it and holds a working range from 40F down to -30F with proper layering. G-Loft keeps its warmth even when wet, which is the whole game on the ice, where everything you kneel on and reach into is cold and damp. Pair that with body-mapped ThermoFloat technology and the bib adds float assistance, a real safety margin on early and late ice when the surface can't always be trusted.

The details are built around the way you actually move on the ice. Integrated Ortholite knee pads cushion every kneel at the hole and hold up to a full season of it. Large two-way leg zips open the bib up to get boots on and off without a fight, and let you vent or reach a layer underneath. A rear zippered hauler pocket adds storage and a spot for hand warmers, fleece-lined zippered hand pockets give your fingers somewhere to come back to life, and magnetic zippered thigh pockets keep tackle and tools fast to reach. A zippered center front storm placket seals the whole system against the wind.

This is cold-weather gear with the same purpose behind everything we make: keep you out longer, focused on the bite, not the forecast.

THERMOFLOAT TECHNOLOGY

Warmth that floats. Movement that doesn't fight you.

ThermoFloat is body-mapped to do two jobs at once. It combines heat-insulating foam with float assistance, building warmth and a safety margin into the same panels, so you get added buoyancy on unpredictable early and late ice without strapping on anything extra.

Because it's body-mapped, ThermoFloat puts material where you need warmth and pulls it away from your joints and high-movement areas. That means you keep full range to kneel, stand, drill, and drag the sled, with no bulk fighting you at the hips and knees. Warmth where it counts, mobility where it matters.
