Product Description

Only a Northwest mountaineering icon like Feathered Friends could come up with a pillow named the Geoduck. Named after the largest burrowing clam in the world, the Geoduck ("gooey duck") is a must have for those who desire a portable and comfortable pillow. Stuff it into its integrated stuff sack while traveling, then pull it out and watch it expand to three times its size when you're ready to catch a nap. Don't leave home without it!
