The Pavillo ToughLite Flex Pillow is crafted with a TPU (thermoplastic polyurethane) & spandex material designed to be soft and flexible yet supportive. Along with premium comfort, this smooth material stays silent, even through natural movement that comes with a great night's sleep. This lightweight pillow quickly inflates for a comfortable night of sleep, and deflates in seconds for easy, compact storage. Use the storage bag for travel or store in any small compartment or gear bag. Weighing only 90 g (3 oz), it takes up minimal space, saving room for all of your other essentials.
