Very happy with this bag. Compact but still surprisingly fits so much! The quality feels good too, durable material even when getting knocked around as a gym bag. Will buy another when the time comes to replace this one.

I was in need of a new duffle bag for work and this perfectly fit the bill. As a personal trainer at a gym, I needed something that provided plenty of storage for clothing, towels, headphones, supplement tubs and food. This bag provides all that with a main storage area and 3 separate pockets on sides. I highly recommend this product.

I bought this gym bag for my husband for Christmas. His previous gym bag was literally dead. Under armour is a very good brand and I was quite surprised by the price point on this bag. It exceeded expectations. It’s a great size to fit all his changes of clothes, towels, shakers etcGood quality with zips and many little pockets. He is very happy! Would definitely Recommend this to others!

This bag is well made and absolutely humongous! It fit enough clothing for 2 adults, with 2 pillows, for a weekend away camping. Partner has taken it away for 2 weeks working and fit all his clothing, toiletries etc and also his work boots, PPE bag etc. When I said this bag is absolutely humongous, it was an understatement! Highly recommend if you're looking for 1 bag to fit everything into. Handy side pockets are good for extra little bits and pieces too.
Good all round bag, shoe pocket is a bit small, i purchased the step down in size first but is couldent fit my runners without having to turn them on an angle. This size just fits them but is a struggle if i put my work boots in.Front pocket is nice but abit slim, molle webbing on sides are grat for keys.Side pocket is good but if you put your wallet in then try to put your drink bottle in the side webbing its abit of a struggle.Inside fabric pocket is good for earphones but too small for sunnies.
Really large. There are no sizes in the description. 101 liter volume 75x36.8x35.9 cmWanted a little less. There is a compartment for sneakers, it will easily fit 5-6 basketballs. Good for not heavy, voluminous sports equipment.
I originally bought the larger version of this bag, has been well used for over a year and still looks brand new. My sister wanted somthing similar but smaller as she doesn't take as much gear to the gym, so I bought her this as a present. She loves it just as much as I loved mine, especially the separate section for shoes.
I needed a small duffle for yhe gym. Easy to grab and go. I keep it packed and close to the door. Perfect. And holds everything I need. Change of clothes, toiletries, workout shoes, towels. You name it, it can fit in this duffel.
My Under Armour Large Duffel Bag is strongly constructed yet light weight. It provides me with the appropriate amount of space to efficiently carry all my martial arts training gear, instructional books, training diary and personal items and hosts a variety of compartments to separate my damp training gear from other items at the conclusion of training.
I just recently purchased the new Under Armour Undeniable 5.0 duffel bag (in medium). I also own the Undeniable Deniable 4.0 (also in medium), so I will review some of the changes from the 4.0 to the 5.0. Before I begin, I will preface by saying that the Undeniable 5.0 is more reminiscent of the 3.0 than the 4.0. Here are the comparisons below:Both medium bags are 58 L, and both bags have the support and stability to stand up on their own while the duffel bag is empty.The 4.0 has the two pockets in the front of the bag for smaller items. The 5.0 mimics the architecture of the 3.0, with one storage pocket on the front and one on the right side of the bag, prior to the water bottle stash pocket.The 5.0 brings back the webbing loops that the 3.0 had, that the 4.0 ... MoreI just recently purchased the new Under Armour Undeniable 5.0 duffel bag (in medium).

The latch that was on the bottom right part of the 4.0 has also been removed on the 5.0.The 5.0 water bottle stash pocket has stitching at the top, in the middle. The purpose of this is to secure whatever items/water bottles you place in the stash pocket. With the stitching, there is only room for a 600 ml water bottle on each side of the stitching; I could not get my 1 L water bottle to fit within the water bottle compartment due to the lack of available space.The shoe/dirty clothes compartment in the left part of the bag has a bit of a larger opening; this provides more convenience to place items inside the compartment.There are a couple of other changes/refreshes/adjustments (cushion strap, interior valuable stash pocket has an Under Armour Undeniable 5.0 logo).All-in-all, I do love both the 4.0 and the 5.0 Undeniable bags, but I would pivot to the 5.0 as the slightly better bag as a result of the refreshes. Under Armour did a great job with the refresh of this bag.
