The Quest women's synthetic mummy sleeping bag is a great value option for weekend warriors and new campers. Entry-level doesn't mean we've cut corners on comfort and versatility. Like all Sea to Summit synthetic mummy sleeping bags, the Quest utilizes WaveLoft construction to allow the insulation to expand out into air-trapping curves for maximum warmth. As the temperature rises, the full-length zipper (which curves around through the foot box) allows you to sequentially increase ventilation to the point where the sleeping bag can be opened flat and used as a quilt. The broader mummy cut of the Quest gives women more room to move and allows a natural sleeping position.
