Like new MR Coulee 20 backpack in black. I used it for a trip to the zoo with my kids to carry rain gear, snacks, and four water bottles. Otherwise, it's sat in my gear locker (closet). Great bag, just need something a little bigger. Size is S/M (I'm 5'6" and 185lbs, but it also fits my 5'10" brother well).
