We have been very impressed with our 22" Stahlsac. It is more than large enough for 2 pair of fins, masks, snorkels, and hand paddles. It also has an outside zipper pocket for wallets, keys, sunglasses, etc. The nylon fabric is high quality, as are the heavy duty plastic zipper, and padded shoulder strap. The mesh upper section is also a good quality vinyl covered fabric, and the bag is relatively light despite the robust construction. It is great for a compact snorkeling bag for 2 people.
Online Scuba was out of stock for this particular bag, but they were happy to order one for me and deliver it within a week.
