The Coolmax sleeping bag liner is made with 100% Coolmax polyester. Coolmax has exceptional cooling and drying properties; the fabric draws perspiration along its fibres away from the skin, providing permanent moisture management performance.
The stretchy fabric is super soft and comfortable, providing greater freedom of movement whilst regulating body temperature as you sleep. Features an integrated pillow sleeve, contact germ guard and Polygiene odour control technology. The anti-microbial treatment is integral to the fibres within the fabric preventing the build up of odour causing bacteria, keeping your sleeping bag liner cleaner and smelling fresher for longer.
Use alone in warmer climates or in conjunction with a sleeping bag for increased warmth and cleanliness.
Comes with a tough ripstop carry case to stow away easily and protect from the elements.
Great product, worked well in summer heat in the UK but it will get a real test in Northern Spain in a few weeks time. I would see no reason why it won't work there just as well. Looks flimsy but is actually VERY strong. Great dry bag included for storing it in and packs away to tiny size so perfect for backpacking when using hostels. Very happy camper here and would most certainly buy again.
