The TomBoy is a great unisex bag for lugging all the stuff needed to get through a day. Great for commuters. It's 16" at the top, tapering down to 11" at the bottom & 14" tall. It has 4 interior side wall pkts, a large, open area and the front flap is also a big, zippered pkt that closes and keeps in place with a magnetic snap. The 2" adjustable strap is very comfy.
