Arc'teryx Aerios Bucket Hat

This bucket – our lightest, most packable shade hat ever – stashes easily in a pack or pocket, so it’s always there when you need it. The highly air-permeable Airshell stretch nylon material helps keep you cool and hugs your head for a comfortable fit, and a single-hand speed adjuster on the back secures it. The headband is super soft and breathable, and the brim is designed to hold its shape.
