Clam X400 Thermal Ice Fishing Tent

The Clam X400 Thermal Ice Fishing Shelter is Clam's flagship hub-style ice fishing tent, engineered for serious ice anglers who demand maximum warmth, space, and durability on Colorado's coldest winter days. The X400's thermal hub design and insulated shell trap heat efficiently, keeping the interior dramatically warmer than standard shelters and allowing you to fish comfortably in temperatures well below zero.

Thermal Hub Design

The X400's thermal shell is constructed from Clam's proprietary insulated fabric that dramatically reduces heat loss compared to standard single-layer shelters. When paired with a Mr. Heater portable propane heater, the X400's thermal construction maintains a comfortable interior temperature even when outside temperatures plunge below zero — the reality of ice fishing on Colorado's high-country lakes and reservoirs in January and February. The thermal design also reduces condensation inside the shelter, keeping your gear dry throughout the day.

Spacious Hub Interior

The X400's hub design creates a large, open interior with vertical walls that maximize usable space. Multiple anglers can fish comfortably inside, and there's room for gear, tackle boxes, and a heater without feeling cramped. The hub frame deploys quickly and collapses into a compact carry bag for transport across the ice.

Multiple Fishing Holes

The X400 features multiple pre-cut floor holes that position anglers over their fishing holes without cutting through the shelter floor. The hole covers keep cold air from entering when holes aren't in use, contributing to the shelter's thermal efficiency.

Durable Construction

Built for seasons of hard use on Colorado's ice, the X400's heavy-duty fabric and robust hub frame withstand wind, snow loading, and repeated setup and takedown without degrading. The shelter's durability is backed by Clam's reputation as the industry leader in ice fishing shelters.
