Patagonia M'S Nano-Air Vest

Sun-warmed rock down low, icy runnels up high: sending temps. Whatever your preferred medium, core warmth matters, and our Nano-Air® Vest keeps pace throughout high-output, stop-and-go missions in variable conditions. Its stretchy and highly breathable fabric package manages variable temperatures to keep you comfortable throughout a range of conditions by integrating the qualities of fleece, soft shell and puffy—now with significant recycled content throughout. Our warm-when-wet THERMOLITE® insulation is sandwiched between a plain-weave liner and a lightweight, weather-shedding nylon shell. All of which means you can put it on and leave it on. The supple feel and full mechanical stretch make for a close, athletic fit over baselayers and an uninhibited range of motion. The left-chest pocket and two handwarmer pockets all close with trim, low-bulk zippers. The center-front zipper has a storm flap and zipper garage to save your chin, while stretch binding at the armholes seals in warmth. Fair Trade Certified™ sewn.
