NeoAir technology changed what people expect from a backcountry mattress. Warm, comfortable and extremely lightweight, our next-generation NeoAir mattress delivers even greater performance than the original. The streamlined shape makes the XLite mattress ultra light and highly packable, while continuing to provide the comfort you need in the backcountry. An extra reflective barrier provides additional warmth without adding weight. Stuff sack and repair kit included.
