The Nemo Fillo Pillow is simply your new best friend. At least on the trail. A combination of air and foam make this travel or hiking pillow comfortable and supportive for even side sleepers. Air is used for volume and packability while the foam is best for insulation and comfort. No matter how full the Fillo is inflated to, one-inch of memory foam keeps the pillow top squishy. If you find you need to add even more height to this Nemo pillow, elastic cord on the underside lets you slide in and hold in place an extra piece of clothing. Let out the air and tuck the Fillo into the integrated stuff sack on the pillow cover for quick and compact stashing. For easy cleaning the pillow cover is machine washable microsuede that is soft to the touch for extra comfort while your rolling around at night. Not just a perfect companion for your head and neck, but also your lumbar when sitting about on a break. Stomach, side, or back sleepers will all enjoy the Nemo Fillo Pillow no matter where they are resting their heads for the night.
