Rated 4 out of 5 by from Almost Perfect When I saw this waist pack I was skeptical at first because I have had bad experiences with other waist packs from Nathan and other companies and there was no reviews on it yet but decided to give this one a try. I've used this pack on two 12 mile runs and this is what I have learned: PROS: 1) Super comfortable. It doesn't slip or sag at all even with the bottle completely full which is what I was most worried about 2)Fits virtually any phone in the front pocket 3)Easy to adjust. The pull tabs on either side are very easy to use even when running 4)Fits tons of gels. The front zip pocket holds 6 gels, maybe 7 if you squeeze them in there. Each side pocket holds 3-4 gels. 5)Looks good. Not a super important factor, but it is nice. CONS: 1) When the bottle is in the back pocket, it leaks a tiny bit of water. Not a HUGE deal, but just know that you will waste somewhere around an ounce or two of water from the bite valve squeezing the back of your waist. I know this has nothing to do with the bottle itself because I own two of the same handheld bottles and they never leak. Other than that this pack is perfect. I will not be returning it to REI.
