Clam's Thermal Trap Technology was the first of its kind providing ice anglers with a new level of comfort. Combine this with similar hub technology used in the industry first Escape Ice series of hub shelters and you will think you've found gold. Well in the ice fishing world we did and that is that Stealth Spearfisher Thermal. It has the head and fishing room comparable to our Escape Ice shelter, but in a full thermal skin. Thermal technology, more headroom and durable hubs and poles make the Stealth Spearfisher Thermal the perfect ice fishing shelter for hard core anglers and their families. And just like the name implies, the dark interior makes this the perfect shelter for spearfishing or sight fishing. The black fabric also attracts sunlight to help naturally heat the shelter on sunny days
