These Ape pants have a generous elastic waist of close to 50 inches and have a hook and loop closure at the back of the ankles to adjust the length. They include foam inserts in the thighs and back to give them a full look. The acrylic fur additions blend into the base polyester material for a full ape-like look but maintain the light weight comfort. Adult, one size fits many. Weight approx. 2 lbs. Made in China.
