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. Read more

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* Read more

5/5 — Perfect for Travel, Gym, or Sports!

I’ve been using the Under Armour XL Duffle Bag for a few weeks now, and I’m genuinely impressed. This bag is a powerhouse when it comes to space and durability. Whether I’m packing for a weekend trip, hauling gear to the gym, or carrying sports equipment, it handles everything with ease. What I love: Massive capacity — The XL size lives up to its name. I can fit multiple outfits, shoes, towels, toiletries, and still have room left. Durable material — The fabric is tough, water-resistant, and handles wear and tear well. Perfect for rough use or unpredictable weather. Comfortable carry options — Comes with padded shoulder straps and side handles, so it’s easy to carry even when loaded. Great organization — Multiple compartments and a vented pocket for shoes or laundry keep things neat and odor-free. This bag is built for performance and looks sleek too. If you need a reliable, spacious duffle that can handle just about anything, this is it. Read more

Nice Bag but Color Slightly Differs

I bought a black camo bag, it is black camo but it is army dark forest green tinted. I don't know how to describe it except that there is a tint to it but it is still black camo. The coloring was not 100% as expected but nonetheless I do like the bag and it is still black camo which is my favorite color combo. I find the size of the bag to be perfect. I got a small which is actually pretty big for a small (make sure you measure before buying the product in any size,) it is as described size wise but I wouldn't call it small. It can fit my gallon water jug because I use it as a gym bag, so it is high quality and durable. I am happy with the quality of the item because my gallon of water is very heavy and if the bag was poorly made they would tear the bag. I can fit several items in all the pockets, which makes it very useful beyond storing my gallon water jug. It also folds up easily if there are no items in it. Overall it is a nice bag, but if you order black camo it does have a green tint to it, which personally I do like. Read more
