Arc'teryx Atom LT Insulated Vest Men's

Get your daily dose of core warmth with the superlight Arc'teryx Men's Atom LT Insulated Vest. Its Coreloft insulation makes the Atom excellent for shoulder season hiking, and you'll definitely appreciate it when your ski jacket isn't cutting it on winter's coldest days. Arc'teryx made the Atom's shell out of a durable Tinthan fabric that has a DWR coating for water resistance. Polartec's Power Stretch material makes the sides air permeable as well as stretchy, and Hardface technology keeps the sides strong for many seasons of mountainous adventures.
