Made from a durable yet soft to touch polyester fabric, this self inflating Thermarest mat, has a compressible foam core, which expands when unpacked for easy self-inflation and for an excellent level of cushioned comfort.

And now, the new WingLock Valve which has been added, which has 3 times the airflow rate of the classic valve to make this luxurious self inflating mat it even easier and quicker to inflate and deflate.
