If you are new to outdoor recreation, or you only camp occasionally, the Trailhead™ synthetic sleeping bag is a great value-oriented option. However, the modest price tag doesn’t mean has cut corners on comfort and versatility. Like all synthetic sleeping bags, the Trailhead™ 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.
