Perfect size for the gym — strong and stylish
I really like this Under Armour duffel bag. It’s the perfect size for the gym — not too big or too small. The material feels durable, and the zippers are smooth. It fits my shoes, towel, and clothes easily, with extra space for small items. I also like how light it feels even when full. The design looks clean and sporty — great quality overall.

Great Bag, perfect for all of kiddo’s karate gear!!
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*

Great Gym Bag with Room to Spare
This duffle bag has been perfect for taking to the gym. I got the medium size, which is probably more space than I really need, but I don’t mind having the extra room. I got the camo design, which I loved when I saw it.The separate compartment for gym shoes is super handy and keeps the rest of my stuff clean and organized. The bag feels durable, and the straps are comfortable to carry.If you’re looking for a gym bag that can hold everything without feeling crammed, this one gets the job done. Just keep in mind that the medium is pretty roomy.

Great Bag for Gym
This duffle bag is perfect! The Under Armour Undeniable 5.0 is super durable spacious, and very well designed. I can fit all my gym gear, shoes, water bottle, and even a change of clothes with no problem. The compartments are well thought out – especially the ventilated pocket for shoes or dirty clothes. The straps are comfortable and the material feels tough but lightweight, so it’s easy to carry around. I also love that it holds its shape even when it’s not completely full. Definitely one of the best gym bags I’ve owned – highly recommend!

Nice bag, and big inside. Nice pocket to carry shoes, but pocket doesn’t take up room if you don’t.
This is a very nice bag. Not sure if the material is as resilient as the Nike Brasilia, which I have in a medium, but we’ll see. The Brasilia also might have the edge for water resistance since the bottom is a rubberized material that wraps seamlessly along the bottom and up the sides moreso than the Under Armour bag, althoug the Under Armour is indeed water resistant. I bought the large in the Under Armour because the shoe “pocket” on the Brasilia is full a compartment the runs the length of the bag, under the main compartment. While this is a nice feature, it makes the main compartment essentially smaller than the overall size of the bag because there’s a permanent divider between the main compartment and the lower compartment. For me, having that feature in a medium sized bag works out great as a gym bag because the main compartment is still big enough to take workout stuff with you, and you can put your dirty clothes and gym shoes in the bottom section after a workout. But, my use for a large size bag is for carrying around multiple jackets and gear as a dog trainer, so I wanted to be able to carry, and find, everything in one compartment, whereas I would have had to separate gear between main and bottom compartments on the Brasilia in order to fit everything in one bag. Additionally, since the UnderArmour’s shoe compartment is on the side of the bag and extends into the interior of the bag, if you choose not to use the shoe pocket the interior of the bag is still the full length of the bag. I recently traveled somewhere for a few days and used the Under Amour’s side shoe pocket, and I still had more room than I needed in the main compartment. And, the shoe pocket is quite large. For example, it fits my Men’s Size 12 Merrell hiking boots, and still has room for another pair of regular shoes. If it matters to you, the interior of the bag is bigger than the opening of the bag – just pointing that out. The only drawback to the Under Armour bag is that the shoulder strap only disconnects from the bag on one side so you can’t completely remove it. In other words, if you want it out of the way, it either dangles or you have to stuff the strap into a side pocket while it’s still connected on one end, which means you can’t close that pocket! What numbskull thought of that design? Might not sound like it’s much of an issue, but it is annoying if you don’t want to use the shoulder strap, so if you’re the type that prefers not to use the shoulder strap it very very much deserves to have one star (if not more) for that dumb design. Hope this wasn’t too much information.

Die UA Undeniable 5.0 hat mich auf ganzer Linie überzeugt. Ich habe lange nach einer Sporttasche gesucht, die nicht nur gut aussieht, sondern auch wirklich durchdacht und robust ist – und genau das bietet dieses Modell!Das Material wirkt sehr hochwertig und ist vor allem wasserabweisend, was mir besonders wichtig war. Selbst bei Regen bleibt der Inhalt trocken – ideal für den Weg ins Fitnessstudio oder zum Training im Freien.Das Platzangebot ist absolut ausreichend: Im Hauptfach ist viel Stauraum für Kleidung, Handtuch, Schuhe und mehr. Besonders praktisch finde ich das separate Schuhfach mit Belüftung – keine unangenehmen Gerüche mehr in der Tasche! Auch die kleinen Innen- und Außenfächer helfen, Ordnung zu halten.Die Tragegriffe und der Schultergurt sind gut gepolstert und angenehm zu tragen, auch wenn die Tasche voll ist. Die Verarbeitung macht insgesamt einen sehr stabilen Eindruck – ich bin mir sicher, dass sie mir lange erhalten bleibt.Fazit: Die UA Undeniable 5.0 ist eine funktionale, stylische und äußerst strapazierfähige Sporttasche – klare Kaufempfehlung für alle, die viel unterwegs sind und Wert auf Qualität legen!
