The Snugpak Cotton liner. Whilst not essential, a loose liner is certainly easier to wash than your sleeping bag. We have a full range starting with liners just to keep your bag clean to liners that will enhance the thermal properties of your sleeping bag. Cotton - a standard in the outdoor market and an essential item if you are visiting youth hostels. It offers easy care and value for money. We recommend this if you have a cotton-lined bag but not for use in pertex-lined bags as it may impair the performance of the pertex. Only available in French blue. Weight: 440g - £9.99
