A sleeping bag liner is an essential part of your sleeping kit. It will keep your sleeping bag clean and it’s a lot easier to wash a liner than a down sleeping bag or quilt. It will add a boost to the warmth rating of your sleeping bag and so potentially allow you to use a lighter and less bulky bag.
These thermolite liners are by far the nicest we have ever used. They are warm, stretchy and very cosy against the skin. They resist odour, pack down very small and dry quickly. Compared to a silk or cotton liner they have far more stretch or give and are a lot more comfortable with the added bonus that they are very robust. We got fed up with having to repair our silk liners but these thermolite liners stretch with you and are not restrictive or prone to ripping. They are perfect for side sleepers.
We started out using these as our cold weather liners, but now just use them all the time. In warmer weather you can sleep in the liner with the sleeping bag opened out over you or do away with the sleeping bag altogether if it is really hot.
At the end of a long day in the saddle they are a pleasure to slide into – sort of like a thinner version of t-shirt material. Thermolite has an excellent warmth/weight ratio thanks to its synthetic hollow-fibre design which offers superior warmth with less weight and bulk. As a highly technical fabric it’s usually the case that it costs upwards of £50 for a thermolite sleeping bag liner, so these represent excellent value.
These are mummy-shaped and dark grey in colour and come supplied in a stuff sack.
