FlipBelt Classic Running Belt, Running Fanny Pack for Women and Men, USA Company

Fantastic product! I've had this for about a month and it is really helpful. I am able to carry my iPhone XS with a case on it, my keys (which have a cord & hook attached to the belt so your keys will not fall out), and a few cards if need be. Whether I choose to walk or run, it doesn't make a difference. Everything stays putAs far as sizing goes, I have between a 34-36 waist & I'm 6'3". FlipBelt recommends that I order a large, but I tried on a large in a store and it felt uncomfortably tight. I ordered an XL it's a great fit. Nice & snug without feeling like it's too tight. If you're on the high end of FlipBelts sizing chart I would recommend going to the next size up. As a side note, I wear this just below my hips and I am slightly "rumpalicous" and my backside is a tad "bubblier" than many guys my size so that may affect how the belt fits meUpdate: 3/23/19: Still an awesome product and really well made. I'm able to smoothly fit my iPhone XS Max, with a slim Otterbox case, and it stays securely inside. What I wrote a couple of months ago is still true, that if you have larger hips or a bubble butt, you can go a size larger and the belt will stay above your hips just fine. Even though I've lost over 30lbs & on my way to 40, and I'm down almost 2 pant sizes, the larger belt still fits well. What I wrote earlier still applies, that if you're near the high side of FlipBelts sizing chart and you have larger hips or a bigger butt, go to the next size upSince I began wearing the belt I prefer it to sit just below my waist, right at my hips & slightly on my butt, and for the most part it stays there. Over the past couple of months I've been getting my 6 miles of fast walking in everyday and the belt does really well. Over this past week, though, I've transitioned to running for almost a mile of that, and combined with my weight loss the belt does not stay where I'd like it and I must wear it around my waist or it will fall off. But it still works fantastically and I would absolutely buy it again just 1 size smaller

I have always had a tough time finding the right belt. They normally bounce around too much or have to be tightened so much to not move that it literally hurts me. This one is absolutely perfect. It holds a small water bottle, phone and keys with no issues. It is super comfy and easy to clean.

I saw this belt advertised in a health magazine, did some research and decided to give it a try. This is the third type of running belt I have tried and it is better than the others by far. My first one was the Nathan running belt (https://www.amazon.com/NATHAN-4807NB-Nathan-Mirage-Black/dp/B00MNAD0PC/ref=sr_1_8?ie=UTF8&qid=1473250378&sr=8-8&keywords=nathan+running+belt) and the second was the Freetoo running pack (https://www.amazon.com/Freetoo-Running-Workout-iphone-galaxy/dp/B015RAOACG/ref=sr_1_1?ie=UTF8&qid=1473250439&sr=8-1&keywords=freetoo+running+belt). The Nathan belt was too thin and the uneven weight distribution caused it to bounce while running, it also caused a muffin tip look. The Freetoo was very similar in that it bounced and rode up seconds into my run and ended up over my bellybutton, but it did offer ample storage and seems to be a good product; just not for running.My biggest takeaway from my 3.2 mile run this morning is that it very much depends on the material of the clothing you are wearing. I had on 'swishy' pants and it BARELY but occasionally rolled up a little in the back (the reason for only four stars) but it never once moved up from my hips; which was my primary problem with the others. I imagine with something like yoga pants or other less slippery materials it would be even better, but even if it rolls a little its better than constantly pushing it down during my run.The width is great, it is lightweight and you can stow your necessities with no worry of losing them. It also fits well under most clothing types. If you don't want anything on your arm and you haven't been able to find the right belt, I believe this may be the one you have been looking for.*For reference: I am 5'6, 165 pounds, and curvy/hippy. My Galaxy S7 fits very comfortably. I ordered a large because I have a 36 inch hip measurement which is in-between the medium and large and it worked out great.I used the size chart that came with the belt and that's shown in the other customer reviews.
