Synthetic bag with many ventilation options; opens flat like a comforter

The Venture women’s synthetic sleeping bag brings new levels of versatility to the realm of synthetic-insulation sleep systems. A full-length right-side zipper, a half-length left-side zipper, and a foot box zipper provide unparalleled ventilation or allow the Venture to be opened completely flat like a comforter.
The unique WaveLoft™ construction allows the Thermolite® insulation to expand out into air-trapping curves for maximum warmth, and the overall shape of the Venture matches your natural sleeping position for supreme comfort.

Designed to keep women warm with:
-- Down chambers filled using body-mapping to maximize warmth for a woman's physiology
-- A wider shape between hips and knees to allow you to sleep in a natural position without compressing the down insulation and creating cold spots.
-- Shorter overall length and narrower girth in shoulders to reduce dead space and increase thermal efficiency
Thermolite® 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.
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
