The bag is well constructed and seems durable. I really like the design. The downside for me so far is that the fabric scratches very easily. It arrived with scuffs and scrapes etched in and I added a few of my own before it even left my house. They don’t buff out so hopefully with time it looks like a patina of wear instead of how it currently just looks a bit shabby. I’ll add that my particular 32 oz water bottle does not fit in the designated pouch. Overall, I’m happy with the purchase, but it’s not perfect.
