Excellent Think Tank quality shoulder bag. If you know Think Tank you know they rank among the best. Holds a lot of gear and is still comfortable. Has outside end pockets for water bottle, small umbrella, sunglasses etc., so you don't have to go into main bag for those items. Includes rain cover. Approx. 18"x8"x10". Water bottle and umbrella not included. Located in the west end. Thanks for looking. Check this thorough review. https://www.youtube.com/watch?v=ISSZPpeCvAU
