Marmot Sphinx 15




“I normally loathe taking packs through chimneys, but this one held up really well to abrasion, and the compression straps on either side make cinching it down easy,” our tester said. Hopping from crag to crag in Eldorado Canyon, she comfortably carried water, two jackets, and a guidebook. With a molded back panel and light weight (20 oz.), it stayed comfortable during an all-day free-soloing and hiking venture in Boulder’s Flatirons, toting shoes, harness, and a hydration bladder between routes. A D-shaped zipper provides easy access to the main compartment, which helps this double as a perfect gym bag.
