Description
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.
Design Details
Technical Features
Sea to Summit uses an anti-microbial finish in two different applications. The internal laminate of Sea to Summit Air Sprung Cell mats is treated with an anti-microbial compound to prevent mold (which could otherwise result from condensed breath moisture remaining in the mat for long periods). The fabric of Expander liners has an anti-microbial finish to keep the knitted poly-cotton fabric fresh and odor free. Both finishes are permanent.

Frequently Asked questions
Does this sleeping bag liner have side zippers?
These sleeping bag liners have two short (12” / 30cm) side openings for convenience, but they do not have zippers.
Does the Traveller pillow case also fit an Aeros pillow?
The Traveller pillow case will fit the regular and large Aeros Pillows, but it's not designed for Aeros deluxe-sized pillow.
Will this sleeping bag liner add warmth to a sleeping bag?
A sleeping bag liner can add a few degrees in warmth to your sleeping bag; however, for optimum thermal performance and cold-weather insulation, check out our Reactor Liner Series.
Is this sleeping bag liner good for backpacking?
Probably not. The Expander sleeping bag liner is heavier and bulkier than most backpackers would want – a Reactor Liner would be more appropriate.
Is the sleeping bag liner machine-washable?
Yes! You can clean your sleeping bag liner in a washing machine with laundry detergent and dry it in a dryer on cool or low heat. However, we don't recommend adding fabric softener--it reduces wicking performance of the fabric.
