Excellent bag however I want to start by prefacing with this with if you're looking for a bag to compete with... probably not the best choice as there is no mini holder, towel holder, and limited overall storage.
To rate it to that standard would not be fair though. This is for casual rounds, practice, for people who want something better than a $15 starter bag but don't want to drop $100. It delivers beyond expectations! Keep in mind that most of this review is based on that this is a budget friendly option.
The materials are very sturdy. I live in CO and am out playing nearly everyday with this bag and setting it down on the rough dry dirt and rocks has not torn into the material at all. The stitching is also of noteable quality and is reinforced at points of high tension to ensure durabiliy. I routinely pick the bag off the ground using just a single shoulder strap or the handle on top and have not seen any wear or sign of stretching there at all.
The shoulder straps are nicely padded and covered with a breatheable mesh material as is certain portions of the back which adds to the comfortability when wearing this in the heat. Really good adjustment range on the shoulder straps also. I'd say even larger people shouldn't have much issue with this bag.
Zippers are also of decent quality. I actually after about 5 months had a zipper break and DD replaced the bag for me under warranty with no hassle.
Drink holder can easily fit even the largest of mugs. I have large yetis and no issue there. Draw string is a nice touch. Has a grommet on the bottom so if you have a spill it won't soil in the holder. Can easily fit two normal water bottles(16.9oz) at once as well.
Storage wise it can hold 20 comfortably. I know it says 2 putters up top but I have no issue with having 4 into there (can squeeze in 5 but not ideal). Bottom can hold about 18-20. There are two side pockets that are okay for small things like wallet, keys, etc. Not enough to carry spare clothing or a towel at all. The compartment can hold the DD disc retriever if you like to bring that along. Also the shoulder straps do have little straps for you to hook sunglasses on which is nice.
If you're not satisfied with the cheaper starter bags and don't want to drop nearly $100 on something for disc golf this is the best option, hands down.
