Sea to Summit Expander Sleeping Bag Liner - Double Size - Stretch Poly-Cotton - Navy

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. 

Antimicrobial protection

All of the Expander Liner series have been impregnated with an antimicrobial treatment which won’t wash out of the liner, and which does not use nano sized particles. This treatment restricts the growth of bacteria and other microbial life which can cause fabrics to smell. Because of this treatment, our Expander Liners are going to stay smelling fresher and will be more hygenic than our standard cotton liners, particularly on longer field trips.

Seamless Construction

The knitted construction of the Expander Fabric means that they are manufactured without a side seam, eliminating a potential source of irritation and a wear point.
