Whether you hike through snow to sleep in an alpine hut or camp out after a summer storm, the Traverse won't let you down. Our unique WaveLoft construction uses thick layers of THERMOLITE insulation looped together to gain extra loft and trap pockets of warm air, providing increased warmth in colder conditions. The baffle construction also eliminates the frustration of getting tangled in loose lining as all lining fabrics are attached to the shell fabric. The 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 provides freedom of movement for both arms, additional ventilation and means the top third of the bag can be folded down as a mini quilt. The full length, two-way left side zip and separate foot zip transforms the bag into a full quilt for when the mercury climbs higher than expected.
