Great bag with a ton of storage and for the price, is a solid step up from a DD trooper or similar. The Izzo is great at standing up on inclines and is comfortable to wear with a couple caveats.
Pros: Tons of space and pockets, Can fit large 32oz water bottles, umbrella, and even a grabber. The exterior material is nice but the inner material is thin and can rip if you're not careful. Massive putter pocket on top that can hold about 5 putters comfortably. Not too hard to put on and take off and has a low center of gravity that helps it stay upright. Discs are very easy to put in and take out of any compartment and offers space to lift up the disc in the bag without pulling the whole disc out.
Cons: The side support inserts are a little tricky to install and feel like you are bending them too much to get them in. It is easy to overload the main compartment and cause the plastic base to sag and dig into your back as you walk. Right now I have ~20 in the main compartment with room for more but more discs would cause it to sag. The Izzo has no feet so this is going to sit right in the mud or dirt which can be an issue because this bag's material isn't 100% waterproof. The base of this bag will get wet and that water will transfer to your lower back as you walk. There is no ridged support between the putter pocket and the main compartment so putters will cause the center to sag a little which could annoy some people.
It might seem like I have a lot of Cons but none of these hinder the use of the bag and aren't an impact enough for me to take off more than 1 star.
