Marmot - Aeroflex Overshirt

This easy, breezy UPF 40 button-up offers layer-friendly comfort for long days under blazing rays.  AirExchange performance fabric is breathable, quick-drying, and sweat-wicking, keeping you in your comfort zone—whether you're kicking back by the lake or pushing into new terrain. When the sun pops out, rely on UPF 40 protection to shield you from harmful UV rays—then snap up the pop-up collar for extra protection on your neck. Multi-day backpacking trip, all-day fishing excursion, or weekend campout? This overshirt is good to go. Dropped shoulders and abrasion-resistant seams keep you comfy, agile, and chafe-free under the weight of your pack or racking sling. Roll-up sleeves let you cover up or cool down as temps change, while two chest pockets—one zip-secure, one VELCRO®—let you stash a light snack for the trail or your phone for that summit selfie.
