Great brand but needs to be better quality. I would pay more for better quality and durability.
Great duffle bag but very flimsy and doesn't hold its structure, The bottom of the bag doesn't have any type of support . Sags when used and material is very thin and not durable. Material easily rips.

Almost perfect!
Love this bag, only wish for 2 things, a "wet item" pocket, and a zipper on the inside pocket. Other than that is is the perfect size, i got the orange and love the color!

Too big doesn’t hold shape.
I bought this bag and I must admit it’s a really nice looking bag! Unfortunately, the medium was on the big size and I’m 6’00” tall they should make it slightly one size smaller. I checked their smaller size but that was too small. My biggest disappointment was it had no support for my items, basically it was a thin vinyl bag. When I placed my items in the bag and used the shoulder strap everything just fell and sagged and sank to the middle of the bag making it uncomfortable, unprofessional and very ugly looking when partially filled with medium weight items it looked very cheap afterwards. Even after I placed a thin plastic board to prevent it from bending in the middle it did not help. For a little more money, I would have gladly paid to have a bag that had much more padded support on the sides To hold it shape and especially the bottom so the bag didn’t look like a letter V on your shoulder when slightly filled. When the bag was empty and on the floor it basically lay flat on the ground like a garbage bag. I hope version 5 is better and/or they make a different better premium gym/duffel/travel bag I’m certain they would sell a ton since many have complained about this bag not holding it’s shape very well. I’m happy with my other UA products that I’ve purchased.

Awesome Duffle
A well designed duffle bag that's perfect for the gym or travel. It's become my preferred carry on rather than the usual suit case. I've bought many suit cases over the years, and this duffle bag can hold more items than any carry on suit case I've ever bought. Once again, another great duffle made by UA!
