I did not want to like this bag at first, but I had some store credit to kill and figured it wouldn't be hard to get rid of the bag if I didn't like it. I've played most of my casual and league rounds with the bag as well as one C-Tier and one A-Tier as well as several field work sessions.
Having used this bag for just over a month now I can say this is very well made. The material is extremely high quality and has held up over the past month of abuse. During my C-Tier we did have some nasty rain and wind I closed the 'front door' and just accessed my discs from the back. It was great and my discs were kept as dry as if I had a rain fly on the bag.
In regards to other bags that I've played with (Pound Rufus, Squatch Legend), the Odin holds up in regards to storage capacity and versatility. I would say that this is on the same level of quality as Pound bags that I've seen and used and is a step above Squatch. I also think that this sits on my back in a more comfortably and with more support than my Squatch, and because of this I've used it for my tournament rounds.
The bonus storage above the main compartment is perfect to shove an extra layer in there which is great for this time of year when the morning rounds are chilly, but an hour in you need to shed the hoodie. Something to note is that when this top compartment is stuff full the main putter pouch, up top, gets really tight and hard to get discs in and out of. If you're just using that compartment for snack, or extra discs I don't see this being an issue for most players. For me, I just put my putters on one of the pockets on the side and use the putter pouch for my snacks, which I always have plenty of. Another small detail that I appreciate is that the putter puches on the side are actually pockets and do not have an open bottom. This lets them serve as additional storage for snacks, towels and other course necessities.
