Just buy a damn Grip. You won't be disappointment. No one will be able to provide you with any different information that what has already been said about the bag. Here are some of my responses to the most common questions regarding Grip bags.
"Has there been any issues with tearing?"
Yes, the 1st run of bags had an issue with tearing and the company replaced anyone who had an issue with them. The 2nd run bag has no major issues reported yet and has worked flawlessly for me the last 8 months.
"How many discs does it hold?"
Depends on what you throw... You can fit 2 putters comfortable in the putter pocket, but will fit 3. The main compartment will hold anywhere from 16-22 discs depending on your high speed/ low speed ratio.
"How does it feel on your back?"
It feels like you are not carrying a bag full of discs and water. Seriously, this thing takes a TON of stress off of your body during long rounds. Adjust it to sit higher up on your back and you feel perfectly balanced when walking. I did 6 months of PT for my back a couple years ago and I can't believe how much weight I can hold in my back without causing any problems.
"I've heard they are IMPOSSIBLE to sit down on the ground without falling over."
Then you're an idiot. Turn the bag parallel to the slope of the hill and it won't go anywhere. They have even fixed the "issue" in the newest of new runs by pushing the supports further apart on the bottom.
"Are these bags really waterproof?"
Yes, the rain cover that is included lets no water into the bag at all.
"Are you able to attach an umbrella or chair to the bag?"
Yes, you can slide them in on the side and they are snug and easy to remove during a round.
"How much storage room is there?"
You can fit a full size hoodie, golf towel, phonekeywallet, two 32oz Nalgenes or 40z beers, snacks, tape/lights, scorecards, pencils, garden seeds, sharpies, bag tags, socks.... blah blah blah
