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 cut of the Traverse gives you room to move, no matter what position you sleep in.
Is this synthetic 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.

Technical Features
WaveLoft™ Construction
WaveLoft™ is a unique construction technology designed to maximize loft and minimalize insulation weight. Instead of conventional flat layers of insulation (sewn flat on top of each other) or shingle layers (sewn in diagonally overlapping layers), WaveLoft™ creates curved layers which expand out from the shell to trap the greatest amount of air possible at a lower overall weight than existing synthetic insulation constructions.
WaveLoft™ is used on all Sea to Summit synthetic-insulated sleeping bags, regardless of price level.
Thermolite® HL-1
Thermolite® HL-1 is part of the family of Thermolite® materials used in Sea to Summit sleeping bags, sleeping bag liners and sleeping mats. HL-1 high loft insulation is a fiberfill constructed with a unique 3D crimp of hollow-core and solid fibers, which provides excellent lightweight warmth with superior durability. The Thermolite insulation lofts up inside the Air Sprung Cells™ of our sleeping mats to prevent convective heat loss from your warm body to the cold ground.
Zip Coupling
Down and synthetic bags identified with our zip coupling symbol use a 65 inch #5 YKK full-length zip which allows a unisex left-handed and women's specific right-handed bag to pair together.
Designed to pair side by side, each person sleeps in their own bag enabling each of you to take advantage of your bag's unique insulation zones, hood and footbox features - perfect for cozy adventures for two.
Bags with full-length #5 YKK zips on both sides can also be coupled together with other pairing bags.
Free Flow Zip
Our Free-Flow triple-zip design ensures your sleeping bag retains maximum warmth and efficiency when needed and multiple ventilation options when it's not.
The half-zip on the right side of the bag (left side on women's bags) provides freedom of movement for both arms, additional ventilation and allows the top third of the bag to be folded down as a mini quilt when the mercury climbs higher than expected.
