Shaped for comfort

Narrower at the shoulders, wider between the hips and knees. Regardless of the position you sleep in (figure-four, on your side or on your stomach), this shape provides a significantly higher level of comfort by giving you the room to move without compressing the insulation.

Warmth from additional insulation

Additional insulation compared to unisex bags, positioned using different body mapping for thermal performance exactly where it is needed. The comfort and versatility-oriented Journey and Altitude sleeping bags have an additional Thermolite layer in the footbox to warm your feet fast. Temperatures for Women’s sleeping bags are shown using the gender appropriate Comfort rating.

Maximum comfort for a good night's rest

Construction details like snug-fitting hoods and oversized draft tubes keep you warm in cooler weather. As temperatures rise, the Free-Flow zipper system of the Journey, Venture and Altitude allow you to increase ventilation up to the point where the bag opens completely flat as a quilt. Super-soft fabrics are comfortable in any season.

You don’t have to narrow your options with a constrictive mummy bag – expand your horizons with a sleeping bag which fits the way you sleep.

Frequently Asked questions

Is this sleeping bag warm enough for shoulder seasons?

Yes. The high-lofting down, cozy hood and draft collar, and extra Thermolite® insulation in the foot box provide the warmth you need for the coldest temps. For more extreme conditions, try the Altitude 15°F sleeping bag and pair it with a sleeping pad that has 3.5 R-Value or higher, like the Women's Comfort Light Insulated.

Is this sleeping bag actually cool in warm weather and summer temperatures?

Yes! This sleeping bag is uniquely equipped with a Free-Flow Zip system, which includes separate zippers on your left and right sides, as well as the foot box, for ventilation. You can also easily transform it into a lightweight comforter for those hotter nights.

Can this sleeping bag be zipped to another sleeping bag?

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