With twelve ounces of top-quality 900 Fill-power Hungarian goose down for warmth and compressibility, 1.1oz/square yard ripstop nylon for low weight, and some of the most affordable prices on the market, the Hammock Gear Burrow is a no-brainer. Other topquilts might run more than $300, and a sleeping bag of similar quality could cost nearly $500
