Not great

Sizing is horrible on these under shirts ... they need to make a fit that fits a XXX man.

Good size for a gym duffle

The bag is bigger than I expected. It says small, but I'd say it's medium to moderately large. On the plus side, I can pretty much bring everything I want to the gym, including lifting shoes, lifting belt, shaker bottle, change of clothes, towel, toiletries, foam roller, baseball, various bands, chalk, mini tripod. It's a tight fit with all that, but it still fits. The separate shoe compartment is awesome. The side pockets are good for small items. There's also an small internal pouch, and a open netted pocket at 1 end to put things you want to easily access. I was hoping for some padding on the strap though, as it's kind of narrow and might be a tad uncomfortable if you're carrying a bunch of stuff. Also, the straps aren't removable, so if they break, I guess that's it.

Great Bag!

Love this bag for going into the gym. With COVID, I’ve been bringing less things these days but when gyms open back up for indoor training, I can easily fit the essentials for my daily in the gym (shoes, shower towel, workout towel, change of clothes, toiletries)

Awesome product

Great products to use everyday and quality was superb

Lots of hidden compartments.

This duffle bag has lots of hidden compartments which I love. Everything can be well organized. You don't have to throw your sweaty clothes with your tennis. You retrieve them through the side. This bag is not oversized; its just right!

Good size

I got it for my husband and he likes it very much, citing good size, not too huge nor too small. It wasn't easy to find one to his liking.

Pleasantly surprised

I was skeptical about getting a smaller gym bag but I was looking for something smaller and more compact that still had separate compartments for quick access ( I may have a little OCD) and this bag is perfect ! The only downside is the side compartment for shoes/wet gear is a little small but still works well as I wear sandals in the steak room and they are flexible so for fine. If you're looking for a compact bag to hold your big and small gear. This is great ! I have attached pics for reference. I am 6'0 210 pounds with an athletic build to help reference the size of clothing I wear.

Great product except

Product overall is good just the side mesh pocket ripped on first use It’s a great bag for the gym especially a side pocket for shoes during winter

Good but a bit too small for me

Overall good product but honestly to me it's a bit too small should have bought the medium one

No shoulder pads anymore

No shoulder pad and adjustable strap is too short. That is really confusing, cos’ the 3rd generation had the pad and the strap was long enough...
