Arc'teryx Thorium AR Jacket

Arc'teryx produces puffies with the same methodical design philosophy and attention to detail as everything else they make, and jackets like the Arc'teryx Thorium AR Jacket are the welcome result. Combining 750 fill down with two weights of Coreloft™ synthetic gives you the right amount of insulation for specific parts of your body, not to mention putting moisture resistant fill where it will do the most good.
