What Our Gearhead(R) Experts Are Saying:"I layered this under a shell on a chilly morning summit push and the thumbholes kept the sleeves from riding up under my gloves. Once the sun came out, the UPF 50+ coverage meant I never had to reach for sunscreen on my arms."Weather rarely commits to one plan, and the Sol Shade Long-Sleeve Crew is built to handle whatever the day throws at it. Worn alone under a hot midday sun or layered as a base on a cool morning trailhead, it adapts without ever asking you to think twice. Moisture-wicking recycled polyester keeps sweat from lingering during a steep climb, while thumbholes anchor the sleeves in place under a pack strap or glove cuff. A herringbone neck tape binding finishes things off, adding durability where the fabric sees the most wear.
