Sea To Summit - Venture I, Women's

  • Sale
  • Regular price $268.95

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.


  • Women-specific, tapered rectangular shape offers more space and comfort than a traditional mummy bag
  • Proprietary blend of THERMOLITE® insulation uses soft microfibers and fine-denier, hollow-core fibers for lightweight warmth, softness, with high loft and compressibility
  • Anatomically shaped footbox offers extra space; thicker footbox insulation increases warmth
  • Oversize antisnag zip draft tubes and neck draft tube
  • Free-Flow half-zip left side, full-length zip right side and separate foot zips offer freedom of movement and increased ventilation
  • 30-denier nylon shell treated with durable water repellent (DWR) and 20-denier nylon lining are lightweight and compressible fabrics
  • Lining fabrics attached to shell prevent tangles
  • Includes strong 70-denier compression sack
  • This bag is designed to zip with another (second sleeping bag sold separately)
