Basically a sleeping bag you can wear around town, the Sierra Designs Women's Elite DriDown Parka offers lightweight warmth and waterproofing that rivals the mummy bag you camp with. A generous dose of DriDown insulation keeps you toasty in the coldest conditions without weighing you down, and it's water resistant so it won't stop insulating the instant it gets a little soggy. The ripstop fabric is light, yet tough, and it's treated with a DWR coating that repels light rain and snow. Raglan sleeves unlock a greater range of motion so you can hike, ski, and climb freely. The adjustable hood can be cinched up around your head and over your chin to create a cocoon of coziness.
