This is replacing a carhartt fanny pack for me. Love the 4 separate zipper pockets. One in the back which is where I keep my wallet. Not too big at all. Separate pockets to keep my stuff organized. I carry my glasses, earbuds, & some toiletries in the separate pockets for just in case scenerios & works beautifully for that. The material seems very durable & there were no loose threads that I found. Can't comment on waterproof since I'm not swimming with this around my body (lol) but if you're just wearing this day to day & use an umbrella on rainy days, you'll probably be fine.
