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.
Our Verdict
The Sea to Summit Venture VtX is a premium synthetic sleeping bag for female outdoor adventurers. The EN comfort limit rating of 0°C provides solid 3-season warmth thanks to the highly efficient WaveLoft Thermolite insulation and women's s-specific thermal mapping.
What sets the Venture VtX apart is its versatile temperature regulation courtesy of the innovative Free Flow zipper system. You can vent the full-length zipper, use the half zipper, or completely open the foot box to let in cooling air as needed. The bag lies flat like a quilt for unrestricted comfort in milder conditions.
The relaxed mummy shape gives extra room where you need it without creating dead air spaces. Female-specific features like the contoured hood and extra insulation over the core maximise warmth. High-quality fabrics balance warmth, packability, and durability.
With its intelligent women's specific design, versatile ventilation, and temperature-regulating Free Flow zipper setup, the Sea to Summit Venture VtX provides excellent three-season performance from a tech-laden, affordable synthetic bag. Venting, opening flat, and regulating warmth prevent overheating while still hitting its 0°C rating when cinched down.
