For the Camper who is looking for a bag that weighs less than 3 pounds, this is the bag that delivers. Ideal for Spring and Fall camping, this 20 degree bag uses Invista Thermolite Extreme insulation (2 layers on the top and one on the bottom) and the shell is made of mini-ripstop, water repellant, windproof Cire nylon. The Cirque is part of the new Alpinismo line from High Peak Outdoors and is available exclusively from CampingMaxx.
