Description

Incredibly versatile, the Altitude women's down sleeping bag is snug and cozy when it's cold, and cool and ventilated when the weather warms. Shaped to match your natural sleeping position the Altitude is both comfortable and light enough to carry anywhere.

DESIGNED FOR WOMEN

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

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 cold weather. For cold weather, we recommend the Altitude 15°F paired with a greater than 3.5 R-Value sleeping mat like the Women's Comfort Light Insulated.

Really cool in summer temperatures?

Yes. The Free-flow zipper system means separate zippers on your left and right side and in the foot box. Open them for ventilation or turn the Altitude into a comforter.

Able to be zip together with another sleeping bag?

The main side zipper can be zipped to Sea to Summit Ascent, Trek or Traverse sleeping bags. The Altitude Regular and Long bags have the same side zipper length.
