I have a couple different models, neither of which show up in current inventory on the site. One has 2 small zippered pockets in front big enough to hold a robust wallet in each, and a velcro flap pocket in between that would hold either a cell phone or pair of shades, and behind them is a zippered main compartment with plenty of space, more than the main compartment on my fanny pack. Dimensions are similar to the larger ones shown. That's the one I use everyday. The other is different in many ways, but structurally similar. I expect to acquire more as time goes by.
