Fireball Hydration Vest with Double Flasks is rated 3.6 out of 5 by 5.
Rated 3 out of 5 by from Size not described accurately Although this appears to be a great, light-weight vest with great pocket and bottle accessibility, the note that it is unisex and one size fits most is pretty inaccurate. I am 5'8"/145 lbs. with a 35" chest and this vest does not fit comfortably. The neck opening and shoulder straps cut in. I really believe this is made for a smaller frame individual only. I had to return it.

Rated 5 out of 5 by from Excellent Basic Pack I've had my Fireball for a year now and love it. I prefer using it with just a bladder and keeping the front pockets free for phone, gels, sunglasses, whatever. Perfect for runs 13.1 or under. If you are looking for bells and whistles then this is not the pack for you. It's basic, light, comfortable and holds up well. Love it for urban runs.

Rated 2 out of 5 by from Hydration Vest did not meet expectation I wore the vest once. While the fit was good, the shoulder strap has zero padding, as a result my left has three large bruises where the skin peeled to my bones. I am waiting now 10 days to get healthy again then I will have to place a towel as padding under the strap. Only wish some foresight went into the designing. The strap is too rough to make contact with the skin. I had on singlets because it is summer time and hot.

Rated 5 out of 5 by from Really Good Running Pack I like me new Fireball vest. It did well on a 25K trail run race this past weekend! Enough storage for essentials and plenty of fluids with two 12 ounce flasks. Really like the product. Shipment came right on time within 2 days. Thank You Nathan! You make a great product. Plus I saw a lot of Nanthan packs on the trail!!!

Rated 3 out of 5 by from Great for hydration and storage but... Hydration and storage are great. I am a smaller framed individual however the shoulder straps really cut in. Especially with the bottles full. The vest bounces and straps will eventually cut into your neck over a 10+ mile run. Definitely need to consider padding the neck area.
