If you're getting into disc golf then I think this is a great first bag. The main section can easily hold 10+ discs (I can just about squeeze 16 into the main pouch) and the top pouch is great for storing a couple of putters. The bag itself is very comfortable and reasonably sturdy, it feels very much like a regular rucksack. The only downsides are that the water bottle holder is a little oversized (I use a cycling water bottle and I really have to pull the cord tight to keep it from wobbling about) and the side pocket is quite small, good for a wallet and phone but not much else. For the price point though, I think it's great value and I imagine will keep me going for quite a while. Can't comment on whether it's waterproof or not as I've only used it in dry conditions.
