This Bamboo liner feels soft to the skin. It can be used as a liner in a sleeping bag and works as a thermal regulator: cool in summer, warm in winter. Obviously, this versatile liner is also useful as a sleeping bag in warm climates. The 'Bamboo Rayon' fibre whisks away perspiration very quickly and is anti-bacterial, anti-fungal and anti-static. The compact liner is easy to clean and quick-drying. Moreover, the Bamboo Traveller Liner is highly durable and environmentally-friendly because it is biodegradable!
