Tired of squeezing into confining mummy bags? Turn to the Teton Sports Celsius XL oversized sleeping bag, an extra-large bag that's ideal for campers of any size. The Celsius XL--which offers a temperature rating of 32 degrees F (or 0 degrees C)--is filled with SuperLoft elite four-channel hollow fiber insulation, which helps keep the chill out on fall, spring, and summer evenings. The bag also offers zippers on both the left and the right side, so you can zip two Teton bags together and create a double bag for couples. Best of all, the bag comes with all the bells and whistles of more expensive bags: shoulder and zipper baffles, an adjustable mummy hood, an interior storage pocket for keys and valuables, and an oxford nylon compression sack for easy packing. The Celsius XL bag comes in black, blue, and olive green colors.
