Roughing it doesn't mean you have to do without basic comforts. Designed with gram-counters in mind, the Sea to Summit Aeros™ UltraLight Inflatable Pillow weighs less than a deck of cards and is compact enough to fit into your shirt pocket. An RF welded thermoplastic polyurethane (TPU) body can be inflated in just a few breaths via a multi-functional Bladder valve. With a super soft stretch-knit 20D polyester face shield, you'll wake up feeling refreshed and ready to face your next adventure.
