A great choice for three season camping or sleepovers, the 30 degree Mountain Trails Sycamore delivers a comfortably warm night’s sleep time and again. “S” quilt construction keeps the 4 pounds of non-allergenic Insul-therm insulation in place and prevents cold spots. The 190T polyester shell and liner is both durable and comfortable to sleep in while the 2-way main zipper allows for venting. The Sycamore can be fully unzipped and used as a blanket or can be combined with another Sycamore to form a double-wide sleeping bag. Comes with elastic roll straps for storage and transport.
