Polar fleece lining, hidden polar fleece inner layer for more thickness, and a polar fleece or cotton outer.
Top part of the hammock is 10" square, bottom 15" square.
Great for a fuzzy pile-up! Will fit one chin comfortably on the top and the bottom, more if they like to squish! Quilted all over to discourage chewing with an invisible layer of polar fleece inside for extra padding.
