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 Designed for Women! I bought this after searching for a hydration vest designed with a women's shape in mind. I also wanted easy access to the items needed during a run. In addition I did not need a super large hydration bladder. This is perfect. No bounce when I run, easy to fill bladder, hose stays in clip when running and easy to drink from. I would highly recommend this product

Rated 5 out of 5 by from My new jetpack I bought this hydration backpack about a month ago to help me train for my first half marathon through this summer, and it has quickly become known as my jetpack. This backpack holds 2L of water (plus a pocket to bring a water bottle), my snacks, & sometimes my phone- I could definitely also fit a light jacket or light long sleeve T in it when I need it. The reason I bought this particular brand is because I had heard they don't move and jostle from side to side while you run... and to my pleasant surprise, this thing does not move at all while I run. I thought I would feel the weight of it, and I barely even notice it- the design is really impressive. Additionally, I thought I would only use this on my long run days, but in this summer heat, I find myself taking it even on my 2-5 mile runs and sprint days. I hate running with anything in my hands, so this couldn't be more perfect for my needs. In terms of sizing, I am 5'4" and 155 lbs, wearing a 34-36C bra, this jetpack fits well on me and has a LOT more room if ya need it. My brother tried it on and at 5'11" 240lbs, he had plenty of room in it too. Highly recommend.

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.

Rated 5 out of 5 by from Fits like a dream Best pack I have ever had! Stays in place. No bouncing and sliding around that in the past packs gave me chaffing. Love all the pockets and all the storage it has. It has enough space for stuff and fuel during a 32km run.

Rated 3 out of 5 by from Love the pack, but... I love this pack — bought it in the midst of training for Grand Canyon rim to rim run. The pack has the perfect amount of adjustment to make it fit you like a glove. Regardless of distance and time on the trail, the pack is still comfortable, no hot spots from rubbing or bouncing of the pack. Disappointed in the bladder though...the nozzle is already leaking and I will have to replace after only a few months of owning. Frustrating.

Rated 5 out of 5 by from fits perfectly I bought this for my wife, as her old hydration pack had become stretched out after many years and miles. The new one fits her perfectly.
