This was the second backpack bag I ever owned, and it made me regret selling my first backpack.
The Good:
-Super comfortable, straps are nice, cushioned, and not too thick.
-Comes with a rain fly which is effortless to install.
-THE TOP POCKET IS HUGE! Room for all sorts of stuff, you can even fit a hoodie with some extra small items.
-The side pockets are big enough for multiple smaller items (phone, wallets, keys, snacks)
-Main disc compartment maxed out at 21 discs for me. Comfortably to get discs in and out I would recommend 18 or 19 discs.
-Side putter pocket holds 2 but you could cram an extra in there if wanted, but it will not be easy to get the putters in or out.
-Comes with a water bladder, a pocket designed for it, and 2 water bottle/umbrella/stool holders for those long/multiple rounds.
-Bag is durable. The bottom is made from ABS molded plastic that holds up well for a long time.
The Bad:
-Unless you fill the main disc compartment tight (18 minimum) with discs, be prepared for discs to fall out of your bag. Lost 2 discs in one day with this bag, because at the time I didn't like to carry a lot of discs. This can easily be fixed by fitting in more discs but, you should not have to buy or carry more discs than you would like for a bag to properly store them.
-The bag as a whole seemed to be top heavy and tip over easy for me.
-Bottom of the bag has ridges for discs which I did not like and it didn't seem to hold the discs any better.
TL;DR: Bag is great, and durable with a lot of storage. But... one negative thing completely destroyed my view and opinion of this bag. I shouldn't have to pack my bag full of discs to stop discs from falling out.
