Product Details

The Sea To Summit 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.
