Keep your money while keeping warm.

Your cool-weather camping just got a huge upgrade in the form of The North Face Aleutian 35-Degree Synthetic Sleeping Bag. Whether you're on the Appalachian Trail or the PCT, this versatile and well-priced option gives you a delightful combination of roomy comfort and warmth for cool nights that dip down below 50F, all without breaking the bank.

Both the outer fabric and lining are water-resistant to protect both you and the bag from damp conditions, while a draft collar and hood drawcord help keep your body warmth in and cool air out when that coastal wind gets a-blowin'. Its Heatseeker Eco synthetic insulation is made of 30% recycled material, is highly compressible for easy packing, and is more durable than other synthetic insulations for warmth on adventures for years to come.
