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 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
sleeping bag. The anti-microbial treatment won’t wash out of the liner and does not use
nano-sized particles. The treatment is approved for use by the EPA (USA) and is used in many
hospitals.
