Sierra Designs Isotope Jacket Women's

Last Spring we gave a couple Isotopes to guides from Alpine World Ascents. The jackets went from Yosemite to Red Rocks, up Longs Peak, and down to Shelf Road. The results? Waterproof-breathable protection and rave reviews for this sub-six-ounce miracle jacket. The Isotope is literally small enough to stuff in a back pocket during a three-pitch route after work. It'll stuff in a jersey pocket for a mountain bike ride above tree line. Whatever your cause, the Isotope stays true, with sealed seams, a full storm flap, elastic cuffs, a drawcord hem, and an adjustable hood. If light is right, then this thing is righteous!
