Sierra Designs Men's Isotope Nano Jacket.
Every spring the guides come knocking, for the lightest, toughest jacket. Designed to be the feather weight waterproof jacket in your arsenal of outwear, this spring won’t disappoint because we’ve shaved two ounces off the Isotope Nano. The updated Isotope is fully backpack waist-cinch compatible and stuffs into its own chest pocket or your hip pocket. Ounce counters and hikers will love the Nano's wispy-light 30-denier fabric and bare-bones approach to features. - Backpacker Magazine, Sept. 10 pg. 54
