green nice sack bag

the sack bag is just for me. I like the function pocket,the volume and the big logo.

Disney trip

I used this on vacation at Disney world! The bag rolled up very small in my suitcase. The bag was big enough and extremely light and well made. The clips made all day use tolerable and a joy. Wish they added reflective material for cars to see you? Nice to add glow in the dark zipper pulls. Little refinements would go a long way. All in all very happy with the purchase!

Repeat Customer

I have bought two of these pack sacks and they have been invaluable to me. I've not had any problems with them. Sometimes the loads that I carry are pretty heavy and I've never had any issues with either of them. The only reason I need new ones is that I wear them out. The only reason that I gave 4 stars is that when I try to use the sternum clip, it is really to tight to fit comfortably. It goes around but just is not comfortable for a larger chested person. I'm going to be getting number three in the next couple of days. I was happy to see the violet colored one as there are so many male colors it is nice to have a female color. Thank you for the quality products.

Depends on what you need

It is largr enough for all my gym items which I like. It is lightweight yet very durable. Comfortable to carry. I would not reccomend the White for everyday use.

Great Product!

Great Product. Currently deployed overseas and this is perfect for going to the gym and carrying my 13" Macbook Air in! The sternum clip allows you to adjust the way it fits on your back and makes it extremely comfortable to carry! Good work UA!

strings not secure enough

I have had 2 of these and the string keeps ripping out of the bottom of the bag . very disappointed in the quality will be returning for the second time and getting a different bag as this one has issues I have other bags just different model numbers and have not had a problem with .


This is my favorite drawstring bag I've ever had. It's built well and seems to hold up to regular wear and tear, but it runs a little big. The bag itself is the size of a regular backpack and the strings make the bag hang low. You can fix the strings by retying them higher up. Aside from that great product.
