Amazing running belt. Value is unmatched. Fits 250ml water bladder.
For the price, this an amazing running belt. I don’t have anything else to compare it to, as it’s my first running belt purchase, but this is the only belt that I will buying moving forward. It has 3 pockets (1 large, 1 medium, 1 small). The small one is perfect for an ID, car fob, etc. The medium one is good for gels, and other items (not big enough for a phone). The large pocket fits my 250ml water bladder perfectly. I don’t carry my phone on runs, but the pocket is big enough to fit a phone, plus a smaller water bladder like a 125ml. The belt sits perfectly just above the waistband of my shorts. I found that is the best position for it. It is extremely comfortable; It didn’t affect my running form at all. There is ZERO bounce, even with a full 250ml bladder, a gel, and car key fob. I ran 5.5mi at 9:00/mi, and it was great. I’ll be buying more colors in the future.

Good belt for running
I’m really happy with this Waterfly running belt. I got the purple one and the color is just as pretty in person. It’s lightweight, doesn’t bounce around when I run, and fits comfortably without digging in. The pockets are surprisingly roomy, I can fit my phone, keys, and a couple of small items without it feeling bulky. The zipper feels sturdy too, which is something I was worried about. Overall, it’s been super convenient for runs, walks, and even quick errands. Definitely worth the purchase, and I’d buy it again.

Great for Running!
This is a great little bag! I run recreationally and this has done the job. It fits my phone, my keys, and tissues or whatever else I need, and I can access them pretty easily. I can cinch it very comfortably with some wiggle room to go, and it still doesn’t bounce. I’m sure there are nicer bags out there, but this is a win to me.

Sizing Doesn’t Seem Accurate
I think the quality of this running belt is actually pretty solid. The zippers are easy to use and it holds my iPhone 16, keys and AirPod case. The only thing that was a bit deceiving was the size. It says it fits a waist that is between 27in - 48in, but mine is 38in and the belt feels tight (and I extended the straps as far as they go). After wearing it on a 3 mile walk, it started to bother me and feel constricting. I can’t imagine it feeling comfortable on any size larger than that. I already took the tag off so I’ll have to keep it, but otherwise I probably would have returned it for one that doesn’t squeeze as much.

Great Running Belt
I bought this running belt in July 2025 (writing this in March 2026). I've done a ton of runs using it and love how much I can fit in it without issue. I carry my phone (iPhone 16 Pro Max), gels, a water bladder, my car key and sometimes more. It does not bounce too much and I honestly forget I'm wearing it most times. I've done 2 hald marathons in it and will keep using it. Best part is I just toss it in the washer and dryer after to clean.

Sleek, secure, and gives me peace of mind on solo runs!
I absolutely love this running belt! As a younger woman who enjoys early morning or evening runs, safety is always on my mind—especially when I’m out alone in quieter areas. This belt fits everything I need: 📱 My phone (with a case) 🔑 My keys 🔒 And yes—my pocket pistol I was a little skeptical at first that something so slim could actually hold all that comfortably, but it totally does. The material stretches just enough to fit everything snugly without bouncing or feeling bulky. I’m especially impressed that my firearm stays secure and discreet the whole time. There’s no awkward shifting, and I feel 100% in control of how it’s carried. ✅ The waistband is adjustable and fits perfectly without sliding around. ✅ The zipper is strong, and the material is lightweight but durable. ✅ It doesn’t scream “I’m carrying something” – it just looks like a sleek workout belt. It’s made a huge difference in how confident I feel going for runs or walks alone. If you’re someone who wants to stay active but also be smart and prepared, this belt is a total game-changer. Highly recommend!

Fits. Good Quality
I use this when I go to amusement parks. I wear it under my clothes. The attendants dont see it and I can keep my phone and car keys in it. I dont have to worry about leaving items where they can be stolen.

A descent minimal running fanny pack with drawbacks
I think the pockets and setup is perfect. It’s nice, flexible and roomy. I wish the smaller pocket was just a little bigger but it’s still descent. My main issue is the strap material which I would have been cool with regular standard back pack strap material(doesn’t feel durable or will last when moisture hits it over time, I maybe wrong) and a standard buckle so that would be easily replaceable. It’s only positive is that it disengaged from the front rather than the sides on a standard buckle. Overall I’d say this is like a 3.5 out of 5 and still a descent offering overall. If you don’t overpack this, it’s perfect for running and minimal setups.

Finalmente un marsupio piccolo e leggero per chi ama correre. Ci va l’indispensabile con la possibilità di inserire una cuffia con filo per ascolto musica.

I bought this running belt recently, and I’m satisfy so far. It’s lightweight and has two zippered pockets. The elastic waistband fits really well and stays in place, making it comfortable to wear. Overall, it’s a solid buy and really handy for anyone who enjoys running

Het bevat ruim voldoende plek voor een grote iPhone, sleutels en kleine dingen. Een flesje water zou er niet inpassen. Doordat het tasje langwerpig is, kan je je spullen strak tegen het lichaam aan gespen en blijft alles goed zitten. Zelfs met mijn zware iPhone beweegt het tasje niet op en neer. Het kan ook goed aangepast worden dankzij de aanpasbare gesp die ook stretch bevat. Enige minpunt is de afwerking aan de binnenkant: veel losse draadjes. Maar te verwachten voor deze prijs. Het stoort mij niet.
