Bristlecone Long-Sleeve Sun Shirt

Above treeline the sun is the weather. A featherweight UPF 50 knit covers the arms all day without cooking them, with a hood that fits under a cap brim and thumb loops that keep the backs of your hands out of the burn. The fabric wicks fast enough to wear on the climb and shakes out wrinkle-free from a stuff sack. Named for trees that have handled worse sun for five thousand years.
