The Sea to Summit Expander Premium Sleeping Bag Liner is made from a premium stretch knit poly-cotton, making it super stretchy and even warmer than a standard cotton weave liner. The stretchiness allows the Expander to move with you as you sleep, vastly increasing comfort and minimizing tangles. The anti-microbial treatment keeps microbial life, thus bad odors, at bay which also helps prolong the life of your liner and sleeping bag. The anti-microbial treatment won’t wash out of the liner and does not use nano-sized particles.
  • 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
