Sea to Summit's 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 Venture™ also features thicker insulation in the footbox, reducing the chance of cold feet interrupting your night’s sleep and a women’s specific tapered rectangular shape that is wider at the hip and narrower at the shoulder. 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 left 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 right side zip and separate foot zip transforms the bag into a full quilt for when the mercury climbs higher than expected.
