What I have here is a rare Travelon dolphin collection bag. This bag has so many compartments it’s unbelievable. What I like is how the pocket on the fin unzips it is perfect for keys and phone. The bag unzips from the front and back to get to the compartments very easy. The measurements are 21 x 9. The strap is 2 inches wide. Which makes it extremely comfortable. The material in nylon so it’s very easy to keep clean.
