Rugged down insulation for cold-weather rock climbing and all-mountain use.

Cold days bring the best climbing conditions—and the Thorium Hoody lets you make the most of them. Designed for durability, this belay jacket features bold baffling stuffed with 750-fill down for reliable warmth, while the rugged mini-ripstop shell withstands sharp rock. Climbing-specific details like a two-way front zip for harness access and oversized internal dump pockets to keep shoes warm between burns make it an essential layer for the chilliest sessions.
