Sea to Summit says: 

The Venture women's synthetic mummy 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 wider mummy shape of the Venture matches your natural sleeping position for supreme comfort

Whatever the weather conditions - make sure you pack this bag before you venture out.

Shaped for comfort

Narrower at the shoulders, wider between the hips and knees. Regardless of the position you sleep in (figure-four, on your side or on your stomach), this shape provides a significantly higher level of comfort by giving you the room to move without compressing the insulation.

Warmth from additional insulation

Additional insulation compared to unisex bags, positioned using different body mapping for thermal performance exactly where it is needed. Temperatures for Women’s sleeping bags are shown using the gender appropriate Comfort rating.

Maximum comfort for a good night's rest

Construction details like snug-fitting hoods and oversized draft tubes keep you warm in cooler weather. As temperatures rise, the Free-Flow zipper system of the Journey, Venture and Altitude allow you to increase ventilation up to the point where the bag opens completely flat as a quilt. Super-soft fabrics are comfortable in any season.

You don’t have to narrow your options with a constrictive mummy bag – expand your horizons with a sleeping bag which fits the way you sleep.
