Under Armour
Undeniable 5.0 Duffel Training Medium Bag

I got the one in pink and it's my new go-to for the gym and any and every overnight! Super spacious, and has a bunch of different compartments which are super useful for organization. Would recommend!

Very roomy bag and excellent quality. I take it to the gym with me every time.

I carry a lot of sports gear whenever I am going to games or practices so I decided I needed to get something with a lot of room. This is exactly that. Can fit all my jerseys and shoes. The material is solid and I haven't had any issues. Also has a sick design I got the black camo/beta color. This bag is big but it also doesnt take up much space so its right in the middle. Overall my best sports bag yet and I highly recommend it.

I was a bit surprised by the huge box it came in. Love the pattern and the design. As a personal item that gets left unattended (secured or otherwise) while doing workouts, I would suggest having a name plate as part of the design? I didn't want to get an all-black bag that could be mistaken for another; and I didn't want a luggage tag dangling. As much as the pattern makes it stand out a bit, a built in ID plate insert would be nice.

I usually get to the gym after work, so I carry my workout clothes and my weight belt, my knee brace and my shoes in my bag. I still have extra room for shower shoes and post workout clothes and shower supplies. Great for a weekend getaway too.

The bag is less than a month old. Already has rip in bag by the main zipper. Very disappointing.

It's a great size for travel

Highly recommended, fits everything you need. A+++

This bag is awesome. It has more than enough room for all your gym essentials. Also it’s well made and tough. You can toss it around and not have to worry about it getting torn up

This bag is deceptively big. Yep, it is a big bag, but it’s got more room than you think. You couldn’t want for more space. It looks great too, along with being durable.

I picked the Black/Beta version specifically for the interior orange lining — it really helps me see what’s in my bag. I was really bummed to open the package to see the plain gray interior. See attached photos. Also wished it had a few more pockets, and I thought it came with a D-ring for key(s, too.

I ordered the Undeniable 5.0, size Medium in color: Black Medium Heather / Black / Metallic Gold. This was a gift. I've never purchased an UA item before. The duffel arrived and I was surprised at the quality and how sharp the duffel looks. Very stylish for a male athlete, with enough pockets and compartments to separate your gear. The medium size is roomy for all your gear plus some. If you are on the fence, I highly recommend making this purchase.

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 had removed. 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.
