The Expander™ sleeping bag liner is made of a super soft and stretchy knitted poly-cotton material. The Rectangular, Traveller and Double models do not have side seams, and combined with the stretch fabric, this offers an unprecedented level of comfort in a budget-priced liner. A built-in antimicrobial treatment keeps odours at bay and won't wash out of the liner when you throw it in the washing machine. This is the perfect travel companion for those looking for a luxuriously comfortable sleep.

• Stretchy, wicking Jersey-knit poly-cotton fabric, knitted without side seams for extra comfort
• The antimicrobial finish keeps the liner fresh and odour-free
• Easy care – no special soap is needed
