What Our Gearhead(R) Experts Are Saying:"I've worn this on some brutally sunny hikes, and the coverage is excellent without feeling hot. The fabric dries fast, the hood stays put in wind, and the odor control is a big win on multi-day trips. It's one of my favorite sun layers for warm, exposed trails."Long stretches of exposed trail feel more welcoming when we're wearing the Mammut Selun FL Sun Hooded Shirt. Built from 100% recycled polyester with UPF 50+ protection, it shields us from intense sunlight while staying light and breathable as the day heats up. The soft pique-knit fabric moves moisture quickly, helping us stay comfortable whether we're grinding through switchbacks or easing into a steady touring pace. A high collar and fitted hood offer extra coverage when the sun sits high or the wind starts to build. Thumb loops keep the sleeves anchored, and the HeiQ Fresh finish helps the shirt stay fresher through long, sweaty efforts. From desert singletrack to bright alpine meadows, the Selun FL Sun Hooded Shirt brings the coverage and comfort we need for warm-weather adventure.
