The Adaptor COOLMAX Liner with Insect Shield is an excellent versatile choice for your buggiest adventures. It will adapt to varied temperatures and humidity and is ideal for use on its own in warm climates, or as a liner in your regular sleeping bag. The COOLMAX fabric is super soft and luxuriously comfortable, kind of like your favorite tee shirt and with its moisture-wicking properties, it will help to provide a dreamy sleep wherever you are.
