Description || Traverse Synthetic Sleeping Bag


The Traverse transitions easily into warmer weather with a full-length left-side zipper, a half-length right-side zipper, and a foot box zipper that provide unparalleled ventilation or allow the Traverse to be opened completely flat like a comforter. In colder weather, the unique WaveLoft construction allows the Thermolite insulation to expand out into air-trapping curves for maximum warmth.

Whatever the season, the wider mummy cut of the Traverse gives you room to move, no matter what position you sleep in.

Frequently Asked questions

Warm enough for cool weather camping or travel?

Yes. The Thermolite® insulation with WaveLoft construction is designed to keep you warm when the temperature drops. For cold rather, we recommend the Traverse 15°F paired with a greater than 3.5 R-Value sleeping mat like the Comfort Light Insulated.

Suitable for summer temperatures?

Yes. A full-length side zipper, a second half-length zipper, and a foot box zipper can be opened for ventilation. In warm weather, unzip fully to turn the Traverse into a comforter.

Able to be zipped to another sleeping bag?

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