Air it out without burning out—this easy, breezy UPF 50 button-up offers layer-friendly comfort for blazing rays. AirExchange performance fabric is breathable and quick drying so you can stay in your comfort zone while kicking back by the lake or pushing into new terrain. When the sun pops out, rely on UPF 40 coverage for protection from harmful UV rays—then snap up your pop-up collar for extra protection on your neck. Multi-day backpack, all-day fishing trip, or weekend campout? This overshirt is good to go. Dropped shoulders and abrasion-resistant seams keep you comfy under the weight of your pack, while roll-up sleeves let you cover up or cool down as temps change. Two chest pockets—one zip-secure, one VELCRO®—let you stash a light snack for the trail or your lighter for the post-hike campfire.
