What Our Gearhead(R) Experts Are Saying:"I've taken the AirExchange SolarShield Hoodie on alpine hikes and desert climbs, and it crushes in both environments. It breathes incredibly well, even under a pack, and the UPF 50 coverage is clutch for high-exposure routes. The scuba hood and thumbholes make it my go-to when the sun's relentless but I still need to keep moving."We're always chasing light and elevation, which means sun protection and breathability are non-negotiables. The AirExchange SolarShield Hoodie from Marmot has become our go-to layer when long days under blue skies are on the itinerary. Whether we're racking up pitches on an alpine wall or pushing pace on exposed ridgelines, this hoody keeps us cool, dry, and shielded from harmful rays. Its ultra-light, recycled mesh fabric wicks moisture fast and dries even faster, while flat-felled seams reduce irritation when we're under a pack or harness. Thoughtful details like the fitted scuba hood, zippered side pocket, and thumbholes help dial in the coverage and utility. This is the layer we reach for when our route gains vert-and the sun won't let up.
