The Trek down sleeping bag brings the comfort of a tapered-rectangular mummy shape and the versatility of a dual-zip ventilation system to wherever your travels may take you. The full-length side zipper and secondary foot box zipper allow you to increase ventilation or open the Trek completely flat like a comforter, and the quality down will keep you warm and snug on chilly nights. The broader mummy cut gives you room to move inside the bag, regardless of your sleeping position. Light and compact, the Trek might just become your favorite trekking / backpacking / travel / camping / down sleeping bag.
