In harsh and remote environments it is important that your sleeping bag works even when it gets damp. The Ajungilak MIT Endurance synthetic fill does exactly that. It stays warm when wet and is very easy to care for.Tents can get humid in the cold Polar environments, leading to high condensation in the tent.  The ShelterTEX outer material is a waterproof membrane, protecting the insulation from this type of moisture
