A new era of highly technical, supremely stylish jackets starts today with the Patagonia Women's Nano Air Insulated Jacket. This trim fitting jacket is filled with Patagonia's revolutionary FullRange insulation. An ingenuous blending of features, this innovative insulation stretches like fleece but breathes like synthetic insulation you've come to know and love. Now, when you're power shopping in Manhattan or powering up a slippery slab, every move you make will be warm and dry, without any extra effort on your part. Nylon ripstop on the outside won't let sharp elbows or crabby granite turn your jacket into tatters. Nylon plain weave on the inside glides over your baselayer with the greatest of ease. DWR all over helps excess water bead up and roll away, rather than sit on the jacket surface and slowly sink into the insulation. FullRange insulation blends the warmth and breathability of other synthetic insulation with the stretch and flexibility of fleece. The slim fit leaves little excess fabric to impede your progress. A lone chest pocket is perfect for cash and credit cards. Two hand pockets hold gloves, lipstick, or a spare bag of trail mix. The mid height collar won't guarantee your safety against vampires, but will protect your neck against a bit of nasty wind. Designed to fill the gap between the R2 and Nano Puff jackets, the Nano Air will leave you actively happy for years to come.
