Firebreaker 6L Hydration Vest is rated 4.0 out of 5 by 6.
Rated 4 out of 5 by from Perfect fit and storage This is the fourth pack I tried in the hopes that it would tick all my boxes: won't ride up on my neck, fits nice and close to my body, fabric is comfortable against my skin and unnoticeable, fits a phone and a couple Clif bars, no chafing or bulk under my armpit. This is finally the one. My only observation is that the fabric is a bit "crinkly" sounding, BUT this was the MOST comfortable aspect of my first marathon! What's more, most of the packs I saw people wearing on the course were Nathan, so there you go.

Rated 5 out of 5 by from Pleasantly surprised. I am a newer runner and started out with a camelbak. Now that I have been running about a year, I need a newer pack with more features for storage. I decided to try the Firebreaker since it did have the front pockets. The very first run, I wasn't that crazy about it, thought well it just doesn't fit my body, but I came home and let out all of the straps as far as they would let out, then put it back on and re-tightened all the straps to my body. That made a huge difference, I love the fit now. It fits my body, it's lightweight, and the water doesn't slosh. If there is anything that needs improving at all would be to put pull strings on the open front pockets. I usually put a sweatband (since I don't like to wear them) in my front pocket, and sometimes I will catch it working it's way out. The zipper pocket does fit my iphone 6 plus without a case with no problems.

Rated 5 out of 5 by from Nathan nailed it! I am 5'3" and have been loyal to Nathan Sports with my packs for 5 years (I had to learn with other brands that Nathan does it better :) ) but my biggest discomfort has always been that the packs chafe my lower back because they sit too low. This one is super light and does not chafe, it sits perfectly! Also, it is lots easier to adjust while running because the side traps pull to the front instead of the back (muscles work better that way). The pockets are bigger than on the other ones I have had, so I don't need as many. The back, lower pocket is easy to reach while wearing the pack. The way the hose clips didn't work for me having the hose coming down on my right shoulder so I swapped it to the left and tadah, it clips best and stays put, no bouncing around like in the other packs. Only thing I disliked is that the mouthpiece doesn't have a closing valve and if you have it ready to run before a race and put it in the car without watching where the mouthpiece is (like underneath something heavy like the pack itself) you might make a big puddle and lose your water before starting. I know, I can replace it but it sucks having to do it. I LOVE that the mouthpiece dispenses more water than the old ones and isn't bitter. Over all, this is my new favorite pack! Where is the men's version? 2L water 6L capacity? :D

Rated 5 out of 5 by from Lightweight I've been using the Nathan Intensity but decided to try this Firebreaker model. Love this one! The fabric is incredibly lightweight and it feels more like a vest instead of a backpack. I love all the deep pockets on the front, especially the large zip pocket that fits my Iphone Plus. Not disappointed at all, just wish it came in more colors!

Rated 2 out of 5 by from Not one size fits most! I am 6’ 203 lbs and pretty fit. This vest didn’t even come close to fitting. I extended all the strapes to the max. Still not even close. If you’re a decent sized person, this is not the product for you.

Rated 3 out of 5 by from Disappointed I was unaware that this item was a womens camel pack. I did not see the description stating womens. So it is to small for me to use.
