When the sun's creeping over the mountaintops, we don't want to stop and reach for sunscreen mid-trek, so we're glad we're hiking in the Crater Lake Long-Sleeve Crew Shirt. Its UPF 50 rating and secure cuffs keep us covered when the solar rays take over the starry morning sky. Breathable synthetic fabrics keep us comfortable as the day heats up, and raglan sleeves give us the mobility we need when we hit the steeper sections of the trail.
