We love this bag!! It seems well made and like it will hold up for a long time, it is well sewn from thick durable materials, the zippers r perfect, and the strap seems well made and I am sure it will hold up unlike others (it even has a thicker rubber-ish material on one side-but not too hard that it's uncomfortable or anything)..we've had it for over a month now and it's been drug around by a 10yr old 2-3 days a wk for classes and still looks just as good as when we received it (as u can tell from pics, it still looks brand new and my kid isn't easy on it, he throws it around everywhere n everything)!! It fits everything we need with some room to spare- all his sparring gear (helmet, foot pads and hand pads) plus his 2nd gi for his jui jitsu class (which is quite large and a super thick material) that he does right after his karate class in the main large compartment (or a kitty with tons of space to spare lol), plus drinks (2 on outside of bag in the dual bottle holder pockets, plus xtra inside the bag), plus he can fit his shoes in the side shoe pocket when he takes them off, the front pocket holds his sweat band with room for other random smaller items, and there's even a small pocket inside the large main part of the bag that we use for his mouth guard (which would also b good for keys and maybe a phone depending on how large your phone is, but there's always that front pocket that is plenty big enough for phones n such too), there's also another zipper pocket on the side with the water bottle holders (that we currently don't even need to use, but I'm glad to have it, I was hoping that this bag didn't only have a zippered pocket on one side- the shoe side- and I couldn't tell from the listing and pics if the other side had a zippered pocket as well, since it had the bottle holders there- but it does, yay) so this bag really utilizes space well with pockets everywhere u need and want them to b, there's no wasted opportunities here!!...there's plenty of pockets and plenty of space for everything he needs and then some, we really could pack more stuff into it if we needed to, but it isn't sooo much extra space that it's too much ya know..it really is the perfect bag, I could see this bag being useful for so many things, and next time we take our yearly trip back home to FL for a cpl wks, we will be using this bag as his luggage for his stuff and I'm confident it will be the perfect size for holding all his things needed for the trip no problem (and I'll get to use that extra side pocket for sure, sweet)!! -The ONLY thing that might make this bag even better, is if it had a hard insert for the bottom (tho it DOES have a thicker PADDED bottom, so it is actually much thicker than the rest of the bag materials, so it not being a 'hard' bottom doesn't actually matter much, actually maybe this is better than the typical 'hard' bottom, cuz it does enable him to squeeze it into the cubbies at the dojo) either way I'm still super happy with this bag, that's just a small note to make.. *If my review was helpful/informative for u, please hit the 'helpful' button below, thanks* ... show more

    • Awesome bag
Color: Midnight Navy (410)/Metallic Silver
UA makes great bags. I bought this to use as my coaching bag for hockey. The Medium size fits my skates, helmet, and hockey gloves just fine. It has the two zippered side pockets, plus the 2 water bottle slots (these really do come in handy) for a little added storage. This is my 3rd UA bag for a reason. They're well built, well designed, and a great value when the're on sale. ... show more

    • Excellent bag!
Color: Black (001)/Metallic Silver
We bought this for my son for a Christmas gift and he absolutely loves it. He does have one just like it, but in a smaller size and felt like the smaller size was too small for him, so he was absolutely thrilled to get one this size! The bag is roomy, and the color is black. Looks just like the ad and the zipper is a good quality. ... show more

Color: Black (001)/Metallic Silver
I purchased this bag because I wanted something to keep all my running clothes in and it fits all of them, including two pair of shoes. My only complaint is I do not understand why the shoulder strap detaches on one side, but on the other side, it’s sewn into the bag even if you stick it into the bottle pocket it’s in the way of the zipper for that end ... show more
