Frequently Asked questions
Is this sleeping bag liner good for backpacking?
Yes! The mummy sleeping bag liner weighs less than 9oz and extends the comfortable temperature range of your sleep system significantly, making it a great addition to your pack. The Traveller version is designed for more conventional travel.
Is this sleeping bag liner machine-washable?
Yes! The Adaptor sleeping bag liner can be washed in a machine with normal supermarket laundry detergent; however, just avoid fabric softeners as they will reduce the wicking performance of the fabric. You can also dry in a dryer on cool or low heat, or simply air-dry.
Does this sleeping bag liner keep you cool while you sleep?
This sleeping bag liner features innovative COOLMAX® fabric that wicks moisture effectively. While this doesn't actively lower temperatures, it prevents you feeling sweaty and uncomfortable when sleeping in humid conditions.
Does the Insect Shield sleeping bag liner protect against bed bugs?
The Insect Shield-treated Adaptor sleeping bag liner is not FDA-certified as protection against bed bugs. You can find details of insects it will protect against at insectshield.com.
