I bought this backpack for my son about a month ago and it is incredibly sturdy. My son uses it for football, to hold his water bottle, snacks, and other items during practice. It gets thrown around a lot and is in the AZ heat during the afternoons. I would recommend this backpack as it is durable as well as, affordable.

This is a great sack pack, if carrying light loads. However, care must be taken if anything heavier is carried since the grommets rip out of the backpack very easily. (See photo) Recommended, but not if you are using for heavier items like school supplies/notebooks. (My son's school does not allow full-sized backpacks to be used during the school day to get supplies from class to class, so they want the smaller sack packs used, instead. This sack pack offers him the most comfort versus a smaller string pack.)
This bag is light and easy. Has two great pockets. One of the best $25 purchases I’ve ever made. I like that it has a couple pockets but isn’t overloaded with them. I use it to go to the gym and soccer.
We bought this bag while at a shopping center for our son to carry his cleats, instead of the store bag. Its a great little BIG bag, not only did it fit his cleats, we were able to roll up two packable coats in the bag.
I bought this for my middle school son, where the school doesn't allow to carry full size backpack. They have to leave it in the locker and only carry what they need in between the classes. Howevere they can carry small sackpack and this was great for carrying couple of 1 inch binders and pencil pouch. It's big enough to carry what he needs but small enough for what school allows. Plus he likes the pocket in the front to put small items.
I bought one for each of my boys to use as their back pack for school, as this particular bag accommodates a 2.5" binder quite well. Unfortunately, during the second week with minimal use, one string has pulled completely apart. Very disappointed. The second bag failed too. During third week with very minimal use, the seam at the bottom pulled apart. My older son mentioned several friends at school had similar problems. I would expect a more durable product from UA; however, Dicks has wonderful customer service!! We returned them for store credit. We will just use backpacks from last year...
My son rides his bike everywhere & needed a bag to carry some of his sports items, water, etc. He picked this out himself & it’s been used every day. The material is durable and it stays put when he’s riding.
The very first time using this the straps came undone and the insulating lining tore when placing a water bottle inside. The knots do not stay tied on these strapsDefinitely not the type of quality expected.
