DESC: Keep cozy during those cool summer nights with the Big Agnes Cross Mountain sleeping bag. If you plan on heading to the desert's of Utah or traveling through the Carolina's the Cross Mountain is insulated with Polarguard Delta so even if the bag gets wet it will still keep you warm. Even though the Cross Mountain is a mummy bag it is pretty roomy that it does require a rectanglar sleeping pad. With a full length zipper you have more control of the temperature for a good night's sleep. Like all Big Agnes bags you do require a sleeping pad that is intergrated with the bag so that you are no longer rolling off the bag, yeh to that. The build in pillow pocket also is great for adding a pillow of jacket. Enjoy your camping this summer.
