The Adaptor COOLMAX® sleeping bag liner will help you adapt to varying temperatures and humidity. The washable, knitted COOLMAX® fabric wicks moisture away from your skin, which helps keep you comfortable as temperatures rise and humidity increases, guaranteeing a great night’s sleep. The COOLMAX® Adaptor liner is ideal for use on its own in warm, humid climates, or as a liner inside your sleeping bag as you transition across seasons, and it's great for keeping your sleeping bag clean and hygienic. It's also available in an Insect Shield® version for extra protection in buggy environments.

Frequently Asked questions
Need special care when being washed?
No - the Adaptor can be washed in a machine with normal supermarket laundry ‘soap’ - just avoid fabric softeners as they will reduce the wicking performance of the fabric. You can also dry in a dryer, use cool or low heat (or better still, just air-dry).
Keep you cool?
Not exactly – the COOLMAX® fabric wicks moisture really effectively. This prevents you feeling sweaty and uncomfortable when sleeping in humid conditions.
Does the Insect Shield version protect against bed bugs?
The Insect Shield-treated Adaptor is not FDA-certified as protection against bed bugs. You can find details of insects it will protect against at insectshield.com.
Work for backpacking as a liner?
Better than a stuff sack – Foam Core Pillows have a handy integrated pocket that doubles as a closure - simply roll your pillow and secure it with the built-in hook and loop closure for easy transport.
