The Comfort plus S.I double from Sea to Summit offers you maximum comfort and warmth on multi-day tours in cooler climates. The thick yet pleasantly light sleeping mat with Delta Core technology protects you from moisture and cold from below thanks to the thermoplastic polyurethane underside. The soft four-way stretch material on the top ensures a comfortable sleeping experience. Thanks to the multifunctional valve, the mat inflates and deflates quickly. An anti-slip print on the underside also ensures that the mat does not slip as lightly. A small repair kit is included for emergencies. All you need now is a climate-resistant sleeping bag and you can relax and get a good night's sleep.
