Sea to Summit Expander Sleeping Bag Liner - Traveller with Pillow Slip Insert

The Sea To Summit Expander liner is made from a premium stretch knit poly-cotton, making it super stretchy and even warmer than a standard cotton weave liner.

The anti-microbial treatment keeps microbial life, thus bad odors, at bay which also helps prolong the life of your liner and sleeping bag; it won't wash out of the liner and does not use nano-sized particles.
