Thermolite Mummy Bag Liner
This mummy bag liner from Sea to Summit saved my weekend this last one when is was snowing when we were camping! It was soooo cold I couldn't sleep! I dug this liner out and crawled into it and into my sleeping bag and was finally warm! Alway carry this liner with you! It could keep you warm during an otherwise freezing night!
This is needed. When u have to be ready, this is a great tool to have.
