Brutal cold weather is where the Arc'teryx Thorium really earns its keep. Packed with 750-fill down and wrapped in a hard-wearing ripstop shell, it's built for long days on the wall when temperatures start to bite. The details are thought through too, including a two-way zip for harness access and oversized internal pockets for warming shoes between attempts. This latest version adds more down, larger baffles and a boxier fit that's better suited to layering.
