Weighing just 4.8 ounces and packing down as small as a 1 liter water bottle, the NEMO Fillo travel pillow makes a strong case for inclusion in your backpack. A combination of memory foam and inflatable air tubes makes the Fillo more comfortable than traditional backpacking pillows. The washable brushed face fabric on the Fillo provides next-to-skin comfort. Integrated elastic cording beneath the Fillo allows you to bolster the depth of the pillow with extra layers. This is an especially functional feature for side-sleepers. The NEMO Fillo has an integrated stuff sack.
