Frequently Asked questions

Warm enough for cold-weather use?

Yes. The high-lofting down, technical hood, oversized draft tubes, and draft collar make the Ascent 25°F and 15°F true 2.5 – 3 season bags. For colder weather, you might choose the Ascent 0°F and pair it with a greater than 3.5 R-Value sleeping mat like the Comfort Light Insulated.

Really cool in summer temperatures?

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

Able to be zipped to another sleeping bag?

The main side zipper can be zipped to the Sea to Summit Women’s Altitude, Journey and Venture sleeping bags. The Ascent Regular and Long bags have the same side zipper length.
