The Sea to Summit Expander Travel 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.

Features:

• Premium stretch knit fabric that can expand twice its width
• Luxuriously comfortable to sleep in
• Extends the life of a sleeping bag by keeping it clean
• Anti-microbial protection keeps liner fresh, hygienic and odor-free
• Double folded and reinforced seams
• Easy care, machine washable
