Description || Trek Down Sleeping Bag


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. A Regular Wide model is available for those who really appreciate the extra wiggle room.

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

Frequently Asked questions

Is this sleeping bag warm enough for cool-weather camping or travel?

Yes, this sleeping bag is great for cool-weather camping. The quality down and 3D hood keeps you warm when the mercury drops. For colder-conditions, try pairing the Trek 10°F bag, which has a draft collar, with our Women's Comfort Light Insulated Sleeping Pad (3.5 R-Value or higher) for maximum comfort and protection.

Is this sleeping bag suitable for warm weather and summer temperatures?

Yes, with a full-length side zipper and a secondary foot box zipper for ventilation, this sleeping bag is perfect for warm-weather camping. For hotter nights, simply unzip the bag to turn it into fully-flat, lightweight comforter.

Can this sleeping bag be zipped to another sleeping bag?

Yes! This sleeping bag can be zipped together with our Altitude, Journey, or Venture sleeping bag models. The Trek's regular and long sizes have the same side zipper length.
