The Marmot AirExchange UPF 40 Short-Sleeve Shirt is a functional men’s shirt built for comfort in hot weather and active outdoor use. It combines classic button-up styling with performance-focused features, making it suitable for hiking, camping, travel, and everyday outdoor wear.

Made from 100% recycled polyester ripstop, the shirt uses AirExchange technology to promote airflow, dry quickly, and maintain comfort during long, hot days outside. UPF 40 protection adds dependable coverage from strong sun exposure, making it especially well suited to summer conditions and extended time outdoors.

For better durability and comfort when carrying a pack, the shirt is constructed with flat-felled seams that improve abrasion resistance and long-wear comfort. A single drop-in chest pocket provides quick access to small essentials such as sunscreen, sunglasses, or snacks.

Its shirttail hem adds styling versatility, allowing the shirt to be worn tucked in or untucked depending on the activity and preferred look. With its regular fit and lightweight breathable construction, the Marmot AirExchange UPF 40 Short-Sleeve Shirt is an excellent option for men seeking a practical and comfortable warm-weather outdoor shirt.
