Clam X-400 Thermal Hub Ice Shelter gives hardwater anglers the room and thermal protection needed for chasing roaming walleye, jigging lake trout, or spreading deadsticks for slab crappies with friends. This 4-sided portable hub delivers 64 square feet of fishable space, so heaters, electronics, and multiple hole layouts fit cleanly without crowding elbows. Two 38-inch Max Entry doors sit on opposite sides, allowing anglers to bank the skirt tight while still walking in with a loaded sled, long rods, or a bucket full of tip-ups. The 900-denier total thermal fabric traps heat, knocks down wind, and reduces condensation, while Clam's industry-leading hubs and heavy-duty poles hold shape when conditions turn rough. Setup goes fast on early ice or mid-winter snowpack, and the shelter packs down easily into an oversized carry bag with cinch strap for dragging behind a snowmobile or hauling in a sled.4-sided thermal hub with 64 sq. ft. fishable areaTwo opposite 38 in.
