The Traverse™ transitions easily into warmer weather with a full-length left-side zipper, a half-length right-side zipper, and a food box zipper provide that 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.
Is this synthetic mummy sleeping bag…?
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 than cool weather, you would probably choose the Traverse 15°F model – pair it with a high R-Value sleeping mat like the Comfort Light Insulated.
Able to be zipped to another sleeping bag? Yes. The main side zipper can be zipped to many Sea to Summit Unisex sleeping bags – Regular and Long bags have the same side zipper length.
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 or to turn the Traverse into a fully-flat comforter in really warm weather.
