Women's Arc'teryx Sunna Speed Bird Crop T-Shirt

High mileage isn't just your route plan, it's how much you'll wear this technical tee. Built for strenuous hikes above treeline, the stretchy, fabric protects your skin when you're exposed on alpine ridges and moves moisture away from the body on steep scrambles and traverses. Relaxed, cropped fit keeps air flowing where you need it most.
