Puffy. Skirt. Two nice words that, when you put them together, make magic. This one's stuffed with super-warm 650-fill down, with a stretchy-soft knit waistband. On your hut trip it takes a pair of base layer pants from looking like underwear to looking like the life of the party. At the Bozeman Ice Festival it keeps your buns toasty while you're sipping beer and waiting for the finals. Oh, and did we mention it zips into its own pocket as a stuff sack?
