Our lightest sleeping bag, and one of the lightest Down sleeping bags you’ll find. Using high quality Duck Down the Downlight range is highly efficient when it comes to weight-warmth ratio. The 660 does not have a tapered shape, so is very comfortable in warm climates particularly with its soft-touch internal lining. The Sleeplight 660 is also treated with Lifeventure Ex3 which will protect your sleeping bag against bed bugs, mosquitoes and the build up of bacteria. Comes with stuff sack.
