Just the right size to cram under an airplane seat, or stuff on the top shelf of a locker, or carry over your shoulder without deep skeleto-muscular trauma. 20″ end-to-end, 10″ front-to-back, 11″ top-to-bottom, with a zipper pocket on the outside and one on the inside. Rip-stop polyester not recommended for those who prefer their bags with holes in them. Rain Defender water repellent not recommended for those who prefer their stuff soaking wet.
