Product Description

Product Description

The Expander Mummy Sleeping Bag Liner from Sea To Summit is made with a premium stretch knit poly-cotton making it super stretchy and even warmer than a standard cotton weave liner. The stretch properties allow the Expander to move with you as you sleep, vastly increasing comfort and minimising tangles. The anti-microbial treatment keeps bacteria at bay as well as prolonging the life of your liner and your sleeping bag.
