Sea to Summit Trailhead ThII is a synthetic sleeping bag designed for camping and multi-day trekking! Trailhead is full of technical features, while maintaining a simple design. Its tapered rectangular shape offers you more space and comfort than a traditional mummy and thanks to the integral side zip and the one on the feet you can open it completely and use it as a quilt. By adjusting the opening and closing of the zip you can also manage the heat and external ventilation, finding the temperature that's right for you! In addition, the hinges are designed to avoid getting caught while you open and close them. A nice advantage that avoids hitches when you just want to rest! Sea to Summit uses the WaveLoft construction for this sleeping bag, which by using thick layers of insulation wrapped together allows to obtain a greater thickness and trap pockets of hot air, thus ensuring greater heat when it is colder. The compression bag is included in the package. It is available in 2 versions:- Regular for people up to 183 cm- Long for people up to 198 cm Sea to Summit Trailhead ThII sleeping bag
