Sea to Summit - Expander Travel Liner

Availability: Out of stock

Stock #: 224P-

The 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 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. The treatment is registered with the EPA.
