The Chumbuddy Sleeping bag looks just like a giant shark and in order to sleep inside, you must slip your body deep into its belly. Will you return in the morning? Maybe. Will you be cozy and comfortable? Yes! Chumbuddy is a stuffed toy, a sleeping bag, and a shark. Each Chumbuddy Sleeping Bag is handmade to exacting standards and yes, it will fit adults, even tall ones. The interior length is a little over 6.5 feet, so Chumbuddy can fully swallow children and average height adults and eat everything but the head of a taller adult.
