Other than your discs, the most important piece of disc golf equipment you have is your bag. Getting a bag you like and that works for your needs is very important. There are over 40 choices of bags available.
I always cheaped out until last year. I used a backpack which just so happened to work very well, but I haven't been able to find amother one with the right pocket configuration. It finally wore out because of cheap materials. This past year I decided to buy a "Real" bag. I went with the "Fadegear" crunchbox (camo). Very nice and a good value. I also recently purchased the "Latitude 64" bag because I needed something larger for those all day excursions, but I haven't had a chance to use it yet due to the snow and cold weather.
