Columbia Shimmering Light Short Sleeve Shirt

This stylish shirt, with its flowing lines and keyhole cutout in the back, actually boasts impressive technical chops. After a winter ascent of Boulder’s Bear Peak left us soaked with sweat, the Shimmering Light was dry by the time we shouldered our packs for the descent 20 minutes later. An airy cut and four-way stretch also bump up the comfort. Cap sleeves let your arms breathe but provide full shoulder coverage beneath pack straps.
