Nathan Hydration Insulated Running Belt Trail Mix Plus - Adjustable Running Belt – TrailMix Includes 2 Insulated Bottles/Flask – with Storage Pockets. Fits Most iPhones (One Size, Blue)

I train for marathons on the street and on trail. I do have to take my phone out of the case, hasn't gotten wet during the rain. I like the size of the water bottles, lightweight, comfortable on the skin, and doesn't move around. The pouch holds a cell phone without its case one car key and a couple of credit cards and an ID card which is fine by me.

While i originally purchased this for running, I’ve found that it’s even more handy for lugging drinks for our kids while walking or hiking.

I really wanted to like this belt, the pocket is a perfect size for my phone and some snacks but this belt made me nuts! To eliminate the bottles bouncing around too much it needs to be as tight as possible which for me is at the smallest setting but I found as my run progressed the belt would get looser resulting in the bottles bouncing around too much and eventually one or both would eventually fall out. I found the bottles bounce less if only have full so I can use it for shorter runs, I need to find another belt for my longer runs - disappointing!

This is my fourth Nathan Trail Mix Belt. I've been really happy with all of them until now. Just purchased this one on June 5th and have only used it maybe six times. Cheap straps holding the plastic bottle holder are fraying. The black stitching is gone and the thin cheap straps are ready to break. I already threw my old one out so I can't compare it to to my older one. I usually get a couple of years out of these things and the belt starts to come apart. This one hasn't made it a month. They must be using different material for the straps now because they are not holding up at all. The slot in the bottle holder where the strap passes through is a little sharp too and I think that's helping to cut through the strap. Totally unacceptable.Very disappointed. I really used to like these belts. Hopefully, they'll go back to using a more robust material in the future. Until then, I'll have to tray another brand.

I'm 5'4" and 115 lbs. The belt was comfortable and easy to resize, but my arms hit the bottles when I tried it on even when placed at varying heights on my waist. It would probably work extremely well for someone about an inch wider than me.

Got this for my daughter to walk with. She loves it.

Excellent. Doesn’t bounce and holds large bottles. Great for distance

I have an older Nathan’s belt that came in a women’s small. This one is supposed to fit everyone and it just doesn’t. The stretchy belt means the fit it too flexible, the bottles fly out while running, and when it’s adjusted to fit a smallish woman (seriously I’m not that small, size 4), the bottles stick out of the side of my waist such that my elbow hits it everytime I swing my arms. It affects my running form and that’s not okay.
