The Aeros Premium Deluxe Pillow is Sea To Summit's largest, most comfortable head bed for backpacking. Air Sprung Cells make sure you don't feel like you're sleeping on a balloon, and the quilted face fabric feels softer than your pillow back home. Sea To Summit affixed a multi-functional valve for easy inflation and deflation from the high-strength bladder. This Aeros is bigger than previous models, yet still packs small for compact storage.
