Description of Patagonia Micro Puff Jacket A water- and wind-resistant, environmentally conscious jacket with high-loft insulation that stays warm when wet. If darkness falls and you're stuck on Hypothermia Ledge, then maybe light wasn't so right. A Micro Puff can save the day (or night): It's durable and warm, even when wet. The tough, windproof Deluge® DWR (durable water repellent) shell houses synthetic insulation that won't clump, separate or drift, thanks in part to the interior quilting design. The jacket also uses more earth-friendly materials – the shell, lining and insulation all contain recycled polyester (40-90% recycled). Features two invisible zippered hand pockets, one internal drop-in pocket and a stuff sack.
