Source: bought it new
Price Paid: around $350 on sale
Great lightweight 3-season backpacking bag.
Have been down in the mid twenties with no extra clothes on, very warm, very roomy mummy shape. I'm 5'9" 200 lbs with plenty of room, packs down small. At a shade over 2 lbs great bag for backpacking.
Have had the bag for about 4 yrs with no problems at all. Thanks.
