Looks good & nice shape. A big size difference from the XS. Plenty of room to fit all my gym essentials in the winter. This includes my jacket, a training belt, towel and water bottle. Would have loved another pocket on the inside to separate my smaller items. A reinforced bottom would also be great so it doesn’t sag in the middle with heavier items.

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.
I really love my new duffle bag. It's the perfect size for a small trip, I use it as a sort of weekender bag. It has very convenient pockets to organize your things, it's water resistant, though I have not yet tested this feature, and it looks amazing. I chose the colour because I like colourful stuff, but also because I figured not many people would have this design so it will be easily recognisible for me in a context where there would be many bags.
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.
From being compressed and squished into the smallest of spaces, to being completely stuffed, this tough, flexible and water resistant duffel bag holds everything together pretty well.This bag is pretty good for general storage, whether you’re someone who carries heaps of stuff to the gym, pool, a camping trip or wherever. It can be packed full to the brim without the zip exploding. It’s light weight when nothing is in it and is also quite flexible, allowing it to be compressed and squished into significantly small places.It has 3 main compartments, the main and the 2 sides. 1 of the 2 sides can be extended to fit more stuff into that compartment by sacrificing a little bit of room in the main compartment. The little extra compartments includes a small fabric ... MoreFrom being compressed and squished into the smallest of spaces, to being completely stuffed, this tough, flexible and water resistant duffel bag holds everything together pretty well.This bag is pretty good for general storage, whether you’re someone who carries heaps of stuff to the gym, pool, a camping trip or wherever.

The little extra compartments includes a small fabric pocket in the main one, a shallow compartment on the front of the bag, and an external mesh pocket divided in 2.The only little things I wish the bag could do is detach the inner pocket from the main compartment and completely detach the long shoulder strap from the bag.
I was supposed to buy the 4.0 instead but the missing shoulder pad for the strap was a deal breaker. It brings added comfort to when I have the duffle loaded with a pair of shoes and extra clothes.I do have to mention two downsides, one of which I have not pinned the root cause just yet:--> The inside (bottom) part of the bag, got wet. I brought it one time for my training and was surprised to see that my plastic envelope along with my bottommost shirts, were already wet (but not soaked), unsure of how the rain went in (hopefully the bottom padding is not that thin). I made sure that all zippers are tightly closed.--> Please refer to the image but for context, I have my coin purse and wallet on this side pocket, so I believe tension while carrying the bag THEN ... MoreI was supposed to buy the 4.0 instead but the missing shoulder pad for the strap was a deal breaker.

Hopefully it doesn't turn worse.
I bought this bag for the gym and for travel. It is the perfect size for both, with room to spare. I bought the small. I’d say it’s more of a medium.It has good sized separate storage options for accessories you may use that the gym doesn’t have, even fits a Pilates ring inside it.I use the shoe compartment for snacks for after the gym to prevent the hangry from setting in.I love the key strap (although not a dealbreaker it would have been nice to have a carabiner included)The straps are very secure and easy to adjust the shoulder strap, the padded section is very nice and comfortable too, no matter how much I have in the bag. The zippers are also very sturdy and glide easily.The dual elastic water bottle holders are great. And the elastic allows me to ... MoreI bought this bag for the gym and for travel.

The zippers are also very sturdy and glide easily.The dual elastic water bottle holders are great. And the elastic allows me to store a collapsible bowl for my service dog too.I’ve been caught in the rain with it a few times and the water resistance holds up, I know my headphones are safe from damage with that and the padded bottom in case of drops.My only con would be that the shoulder strap is not removable and is attached right next to the zippers of the side pockets so sometimes gets in the way.Also nothing to do with the bag but only having standard post as an option, I live in a rural area so express is preferred. Would be nice to have the option of both for people who don’t live in cities.Have not yet traveled with it but using it every day for the gym I am confident it would be very suitable.All in all I am very happy with it and glad that I bought it.One of my images shows a jacket, gym towel, headphones, gloves, resistance band and my service dog’s vest and lead in there with plenty of room to spare.
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.
