Rated 5 out of 5 by from Great hydration pack for petite women! I’m 5’0â€ and I wasn’t sure this pack would work for me. I was so happy when I put it on and was able to adjust the chest straps to fit either high on my chest or lower around my rib cage. For me the lower choice was perfect. It adjusts super easily for the best fit. I was able to load it up with everything I needed for a longer run. The only downside I found was if I want to take my iPhone, I have to pack it in the back part, which isn’t really a big freak since I have an Apple Watch to control my music. I would love to see some type of clip attachment that could go on the front to hold my cell so I can have easier access! Overall, I’m so impressed with this pack! I highly suggest it!

Rated 4 out of 5 by from Love the fit! I've had this pack for about a month and run with it about twice a week. It fits very well! I read other reviews that emphasized clipping the chest clip first then tightening the rest, and that's absolutely the best way! I think my bite valve was defective from the beginning as it leaked when I ran. I emailed Nathan's support service and got a response immediately stating they'd send out a new bite valve at no cost. I should be receiving that soon and hope it will stop the leaking. Overall this pack is great, it doesn't bounce. I use the front drawstring pocket for my phone and the other zip pocket for other small items. The back pocket fits my ID and a snack if you want. The bungee cords on the back can also hold your jacket.

Rated 5 out of 5 by from Love this pack! No rubbing or bouncing. The blue color is adorable. The straps stay in place and you can fold up the excess really easily if needed. The bladder that comes with it is a little awkward to fill on the go, but otherwise works really well-- no leaks.
