The North Face Eco Trail Synthetic 35 Sleeping Bag is a versatile sleeping bag for camping, overnight trips and weekends in the backcountry. Rated at 35°F, you'll be cozy in mild spring, summer and fall weather. Not only is the shell made from a recycled polyester ripstop fabric, the synthetic insulation is also recycled. Three cheers for nature while you explore nature. The J-zip wraps around at the foot end, making venting fast and easy, especially when your toes start to heat up. Cinch the hood cord closer on colder nights and the draft collar offers extra coziness and prevents heat loss.
