The Expander sleeping bag liner is made of a super soft and stretchy knitted poly-cotton material. The Rectangular, Traveller and Double models don't 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 odors at bay - and it won't wash out of the liner when it's thrown in the washing machine. This is the perfect travel companion for those looking for a luxuriously comfortable sleep.

Frequently Asked questions
Have side zippers?
No - the Traveller model has two short (12” / 30cm) side openings. They also have pillow slips.
Does the Traveller pillow slip fit an Aeros Pillow?
Regular and large Aeros Pillows will fit. Not the Deluxe sized pillow.
Add warmth to a sleeping bag?
They will add a few degrees; however, for thermal performance, you may want to check out the Reactor Liner Series.
Work for backpacking as a liner?
Probably not. The Expander is heavier and bulkier than most backpackers would want – a Reactor Liner would be more appropriate.
Washed in a washing machine?
Yes - you can wash your liner in a machine with normal supermarket laundry ‘soap’ and dry it in a dryer, using cool or low heat. Fabric softeners will reduce wicking performance of the fabric.
