Lighter in packs and lighter on the environment, The North Face Trail Lite Sleeping Bag's minimalist design uses recycled materials. The recycled 650-fill power down packs down small and offers good warmth for the weight, letting us travel lighter while re-using natural materials for a lighter environmental footprint, too. That's also true of the recycled face fabric and lining, which reduces waste while giving a soft base for a good night's sleep. The mummy design also cuts down on weight and bulk while still protecting you down to 35 degrees Fahrenheit. That light and lofty mix covers backpacking trips and camping trips for much of the year.
