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.
