Patagonia Nano-Air Light Vest - Women's

The Patagonia Nano-Air Light Vest is built to stay on through an entire aerobic mountain day, climbing hard one minute and standing at a belay the next. Stretchy FullRange insulation dumps heat when we're working and holds it in when we stop, so one vest covers both ends of the effort without a layer change. A low-profile pattern keeps full range of motion through the arms and shoulders, so the extra warmth never gets in the way of movement. What Our Gearhead® Experts Are Saying:"I've stopped packing a second layer for approach and climb days. I'm sweating through the scramble in and warm again by the time I've clipped into the anchor, all in the same vest."
