The Big Agnes Big Pine sleeping bag can be used anywhere, at home, in the yard or at the cabin. The Big Pine is designed to be roomy and spacious all the while keeping you warm with 25 oz of 600 DownTek water repellent down. Use it zipped together like a rectangular bag or unzip it and you have 80 x 70 inch down comforter. Sleep easy, with the quilted baffles, you won't have to worry about the down shifting around in the bag. The Big Pine bag is perfect for cool early and late summer nights when the breeze off the water is just enough to need a light yet warm bag.
