What Our Gearhead(R) Experts Are Saying: "I love these shorts for big summer missions-they breathe incredibly well and dry even faster. The waistband feels soft but secure, the pockets are super easy to access with a pack on, and the UPF protection really helps on exposed trails. They're lightweight without feeling flimsy, which makes them perfect for long, hot days outside." We reach for the AirExchange SolarShield 4in Short when the trail heats up and we want to keep moving. Marmot's AirExchange fabric is engineered to stay cool and dry even on the hottest days, giving us breathable performance that doesn't hold us back. With UPF 40 sun protection built right in, these shorts help shield our skin from intense midday rays during hikes, climbs, and quick-fire trail runs. The encased elastic waistband and internal drawcord make it easy to dial in a comfortable, stay-put fit, whether we're layering or going ultralight. Angled hand pockets stay accessible under pack straps or a climbing harness, while a zip-secure back pocket keeps keys or a phone safe when the terrain gets scrambly. After long days outside, a simple hanger loop lets us dry them out anywhere-from a tree branch to the tent line-so they're ready for the next adventure.
