Men's Variant JacketThe insulation piece that breathes where you need it to. Here's the problem with most down jackets: they put 800 fill everywhere, including your underarms. Great for warmth, terrible when you're moving. You overheat, sweat pools in the pit zone, and suddenly your insulation is working against you. The Variant Jacket solves this with strategic material placement. 800 fill goose down on your chest and back where you need maximum warmth to weight.
