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!

Great gym bag.
Bought for my husband to take to the gym before heading to work. It fits his work out clothes and shoes. Along with a towel and a change of clothes for work. It’s the perfect size for his needs he stated. And was very pleased with the looks and functionality.

Fantastic quality!!
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.

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.

Love this.
A very nice looking and well made gym, and travel bag. It has enough room to store a bunch of clothes and has a separate zipper area on the left end for your shoes. Recently, I used the bag for my Ghost Hunting gear and clothes. It was perfect! Plenty of room! You can carry by hand with the two straps or an over the shoulder strap. Very comfortable to do so. Under Armour is a great brand! Will buy again.
