The quality is really, really good. However it is too small. I purchased the medium size and put in a water pack inside from an old bag (I was able to put water tube through the bag with no issue at all). It’s very comfortable and can hold a good amount of items, snacks, water, electronics, etc… However, it is too small. I am male, 5’6, 200lb and it fits me good, but I struggle a bit to take it off. But while it’s on, it’s very comfortable, sits high on my back/shoulders which allows me to move more and lets my lower back breath. Maybe as I lose weight and tone myself it’ll fit better; but for now, buyer be aware that it is on the smaller size side.

if you plant on running and dont like putting stuff in pockets then these are for you
