Bouldering, hiking, camping, and trail running—we can squeeze a surprising amount of activities into our day when we're wearing the Crater Lake Crop Zip Top from Mountain Hardwear. This 1/2-zip crop top is made from a stretchy, wicking, and UPF 50 sun-protecting fabric blend for warm-weather comfort, and is treated with HeiQ Fresh technology to keep funky odors at bay while getting after it on the trail.
