The Arc'teryx Men's Cormac Hoody is built for high-output mountain activity in hot conditions, delivering lightweight comfort, moisture management, and breathable coverage in a streamlined technical layer. Its recycled polyester Solotex waffle fabric feels soft against the skin while wicking moisture, drying quickly, and helping resist odor through long active days. A regular fit promotes airflow and reduces chafe, while low-profile merrow stitching and a laminated collar help maintain comfort. Thumb loops provide added coverage for hands during cool starts or extended sun exposure.
