Sea to Summit Trek Down Sleeping Bag 650+ Ultra Dry Down

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 the sleeping position you may adopt. A Regular Wide model is available for those who really appreciate extra girth.

Light and compact, the Trek might just become your favorite trekking / backpacking / travel / camping down sleeping bag.
