This bag handles various needs.

A comfortable bag that holds more than you think. You can carry shoes/cleats or your gym clothes or a weekend getaway. And you can store away eaily. [This review was collected as part of a promotion.]

Sack pack

Bought the pink color for valentines for my wife. She works out every day and I want her to match with her under armour apparel. I was surprised how durable and thick it is and now she uses it for her workout gloves, knee pads, and jump rope. If any drawback it does not have an exterior pouch for her water drink but it is a great gift add on item. [This review was collected as part of a promotion.]


Best "sack pack" around. Comfortable to use, plenty of room. It will be much more useful than a regular sack pack. It will not only be useful as a quick overnight bag, but as a catch all bag when visiting a theme park.

Nice Size Comfortable Bag

Purchased two of these bags, one for myself and my partner. I use mine for my gym gear, fits everything needed comfortable. Trainers are a squeeze but they are an 11. Wouldn’t over load bag but is comfortable with the right weight in it. Partner uses hers for books and work stuff. Holds on back well but most comfortable when using the two handles

Excellent Product would recommend to anyone

Excellent items very useful, comfortable and easy to use

Good gym bag!

Wish it had a drawstring bag attached on the inside so that shoes could be kept separately but that is my main complaint. The material the bag is made of is so thin I would not recommend it for a heavier load but is great as a standard gym bag. So comfortable to carry!


I don't do a lot of reviews but this one deserves it. I purchased this for my 11 year old son. He goes though a ton of those sack bags because the strings break or the hole rips. He also complains about the straps digging into his shoulders on the regular bags. I purchased this one because of the "real" straps, and I'm not disappointed. The straps are padded along with a light padding in the back of the bag. This bag is not noticably heavier then the regular sack bags and it does have a nice zipper to hold everything inside. The pictures on the web site also do not show the zip around expandable part very well, but once it is open it probably adds about 2" all the way around the bag. This zipper when not opened also supports the weight of the bottom of the bag. I know this bag is a little more expensive then the other bags but in my opinion it is more then worth it. Whomever thought of this bag, thank you, it's perfect for my sons needs!!
