The Arc'teryx Caliber zip neck pullover provides lightweight insulation for hiking, traveling and lounging. Light Polartec fleece has a refined corduroy appearance; fabric wicks moisture, dries quickly and is breathable. Quarter-zip collar lets you control ventilation. Laminated sleeve pocket with laminated zipper secures small essentials. Gusseted underarms allow you to stretch and reach without the hem lifting. Contrasting trim adds appeal.
