My husband and I are soccer coaches, and this bag is large enough for all our gear; cones, pennies, first aid kit, ball, and much more. This bag has many pockets to keep everything organized.

Very versatile bag. It’s big enough to hold a wife variety of things, but also easy to carry.

Perfect carry size for the gym and toiletries, or a weekend with a soft inside pocket for delicate items like earbuds or a small speaker.

Durable Gym Bag

Originally posted on Under Armour

Yes, I recommend this

I would stack this gym bag against any other brand’s expensive line of bags. The material on the outside is moisture-wicking and durable. The black and white is a classic look. You can fit a bunch of clothing in here. The side pockets for water bottles is a nice touch. You can’t go wrong with this bag if you’re looking for something to use everyday.

Substandard Quality

Originally posted on Under Armour

No, I don't recommend this

Bag is made from substandard (thin) material or process. Material is unexpectedly thin for its purpose and does not stay open on it's own as per marketing claim. Exterior pockers sized far too small to be useful. Zippers do not operate smoothly. Overpriced for the Quality of item and likely is NOT durable enough to last in normal+ use.

Hi, there! Sounds like our duffle wasn't durable enough and that our zippers didn't perform the way you wanted. We totally understand your disappointment and appreciate you and for calling this out. I'd love to suggest other options that may work better for you, like our Men's Project Rock Duffle Backpack. I'll send an email shortly to get more details and help you find the perfect bag! Talk to you soon!
