Sea to Summit Quest Women's Synthetic Sleeping Bag 30

The Sea to Summit Quest Women's Synthetic Sleeping Bag 30 is a women's mummy-shaped synthetic bag with a -1°C comfort rating and -7°C limit — a standard three-season range. WaveLoft Polyester insulation retains its warmth better than down if it gets damp, which matters on humid routes or where drying gear on the move is difficult. A full-length, two-way zip on the left lets the bag open flat and double as a quilt, useful on warmer nights or simply for ventilation. A 30D DWR-treated nylon shell paired with a 20D nylon liner is the standard combination for this category, and a stuff sack is included. The reliability of synthetic fill in wet conditions comes at a weight cost: 1340g and a weight-per-degree figure of 191g are noticeably higher than comparably warm down bags. The Quest 30 is a practical choice for damp climates or tighter budgets rather than a bag aimed at ultralight trips.
