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*

I scaled up after having a very small gym bag for years and this one did not disappoint. It's very roomy and can easily hold 2 pairs of shoes, gym and/or work clothes, a pack of electrolyte powder sticks, glasses, a lock for the gym locker, plastic containers of protein and preworkout powder, a blender bottle, another water bottle, and other miscellaneous stuff and STILL has a lot of room leftover. It's durable and has a good amount of pockets/extra spaces, though there isn't anywhere besides the shoe compartment to easily separate out sweaty clothing except for a mesh compartment on the outside of the side pocket, which is where I usually put my armband and headband after a workout. It's very easy to fit a wet bag in, however. The material all feels sturdy but is also very easily foldable to fit in your car and gym locker even when you need to squeeze it into a slightly smaller space.

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.

I recently picked up the Under Armour gray and black gym bag, and it has quickly become an essential part of my fitness routine. From design to functionality, this bag checks all the right boxes. Design & Build Quality The sleek gray and black color scheme is modern and versatile, making it perfect for both gym use and casual travel. The bag feels incredibly well-made, with durable materials that stand up to daily wear and tear. The water-resistant finish adds an extra layer of protection, which is especially helpful when dealing with unpredictable weather. Storage & Organization This bag offers plenty of space without being bulky. The main compartment is roomy enough to fit a change of clothes, shoes, a towel, and even some extra gear. It also has multiple zippered pockets for smaller items like your phone, keys, and wallet. I particularly like the ventilated shoe compartment—it keeps my gym shoes separate from clean clothes, which is a game-changer. Comfort & Convenience The padded shoulder strap is adjustable and comfortable, making it easy to carry, even when fully loaded. The dual carry handles are reinforced, so I don’t worry about them wearing out over time. Overall Impression Under Armour nailed the balance between style, durability, and functionality with this gym bag. Whether you’re a serious athlete or just someone who hits the gym a few times a week, this bag will meet your needs. It’s practical, looks great, and holds up well under daily use. Would I recommend it? Absolutely. If you’re looking for a reliable gym bag that’s both stylish and sturdy, the Under Armour gray and black gym bag is a fantastic choice.

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.

It’s a great gym bag. I’ve also used it for overnight stays. I got the medium size, which is perfect for the gym and carrying shower items and towels and water bottle and shoes/clothes. The small size is great if you only need gym clothes without the shower stuff. I would get a larger size, however, if you plan to use it for traveling or week-long overnight stays. I like the quality and durability, as well as the pocket access. I would prefer more pockets, but that’s just me. I appreciated the variety of colors to choose from, too.

I recently purchased the Under Armour Undeniable 5.0 Duffle in X-Large for my son’s trip, and it was exactly what he needed for a carry-on! The bag is spacious, offering plenty of room for all his essentials—clothes, shoes, toiletries, and even his laptop. The X-large size was perfect for a carry-on, and he was able to pack everything without worrying about overpacking. The material is incredibly durable, giving him peace of mind as he tossed it around during travel. The black and metallic silver design is sleek and stylish, and it’s so easy to spot on the luggage carousel. The padded shoulder strap made it comfortable to carry, even when it was packed full, and the top handles made grabbing the bag a breeze when he was in a hurry. He also loved how well-organized the bag is. There are several pockets, both inside and out, making it easy to separate smaller items like chargers and toiletries. The zippers are strong and smooth, and the bag feels solid and well-built overall. If you’re looking for a spacious, durable, and organized travel bag, this duffle is a great option. It worked perfectly for my son’s trip, and I highly recommend it.

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.
