Sea to Summit
BreakdownWhether you are expecting the temperatures to drop past the comfort level of your sleeping bag or you just sleep cold, the Sea to Summit Thermolite Reactor Sleeping Bag Liner is a great option. Its hollow core fibers trap heat and offer great insulating properties, improving the temperature rating of your sleeping bag. It's also soft and stretchy, making it very comfortable.
Sleeping bag liners also help improve the life of your bag by keeping dirt and sweat away from your sleeping bag. When down gets dirty it becomes less efficient. By using a liner you can keep your bag cleaner and the liner is much easier to wash than a sleeping bag. This liner will help you sleep through those chilly nights on the mountain and prolong the life of your sleeping bag.
I love this liner. Absolutely love it.
