The 4-season sleeping mat is optimized for our tents, designed to keep you warm and give you a comfortable sleep during all seasons. The width, length and thickness are optimised to fit today's modern tents and our increased comfort requirements. Features loops for connecting the Air Pillow. Includes a pump bag/stuff sack for easy inflation and storage. The mat also has slightly higher edges to create a cradle to keep you on the mat during the whole night.
