        Makes me feel safe

        So I'll be honest, the main reason I got this particular fanny pack was for the color. I don't love neon green, but I do love feeling safe on the road when it starts to get a bit dark out. It shows up easily, especially when light shines on it. So I feel a lot better on the road. The fanny pack itself is great, very snug. Fitting my phone is is quite tight, but at the same time that means it's not jiggling around while I run.

        Amazing value, especially for the low price.

        Wow - amazing quality for such a low price. VERY nice quality materials. The sides and front are a very nice quality spandex, and well constructed. The back is all velcro which makes it highly adjustable to fit most people AND it came with an "extender" piece for extra-larger folks....very thoughtful.As a few others have mentioned, the front pocket will hold _most_ smart phones, even the "Pro" and XL versions, IF you don't use a wallet-style case, as I do....I have an iPhone 12 in a wallet case with a strap, and it JUST fits in the pocket but I don't zip it so that I don't over-stress the zipper, however it still holds my phone very securely so I'm not worried about accidental slips or drops, even while running. It also has a couple of smaller extra pockets for whatever else you might need to carry with you, like a car key or credit card/cash.Overall a great design - exactly what I was looking for, a slim, snug belt with pockets rather than the old style "fanny pack" - that is very well made with nice quality materials. I'm very happy with this

        Not Your Mom or Dads Fanny Pack!

        This is the perfect fanny pack! It doesn’t cause any sweating and I barely knew I had it on. I enjoy the vibrant colors and stylish design. The material feels soft against my skin and clothing. The extra extension strap worked perfect for my waist size. I’d been searching for this type of waistband for a while but none had the extension for a larger waist. I was elated to have found this one. There are enough compartments to carry everything I need. Because I also keep money and my ID in my fanny pack, having the extra pocket compartments is a lifesaver.My husband can also fit into this fanny pack. I allowed him to use it “once”. He really enjoyed it and the only different thing he carried was a tall bottle of water. I use a small bottle of water only because I don’t like the weight of a taller bottle. One time I spilt water inside of the fanny pack because I didn’t close my water bottle lid properly. My clothes stayed dry the entire walk and didn’t notice the water spill until I got home. I was able to paper towel it dry and let the pocket air out. Wiping it dry was all it needed but I went the extra step to air it out too. There was no staining and no mess.

        Comfortable running belt

        Quality belt that fits my phone and headphone case for my runs! It is very similar to the popular Flipbelt but for about half the price. As others have mentioned, it could also double as a money belt if you are traveling which is an extra perk that there are more uses for it.

        Slim, lightweight, and versatile waist pack perfect for workouts, running, and travel

        The WATERFLY Running Belt Fanny Pack is an excellent slim and lightweight waist pack designed for both comfort and practicality. Its versatile design allows it to be worn discreetly under clothing for added security or over clothing during activities like running, jogging, cycling, or hiking. The main zippered compartment is spacious enough to accommodate larger smartphones, though its slim profile makes it best suited for flatter items rather than bulkier objects.Two additional side pockets provide convenient storage for smaller essentials like keys, cash, or cards. While these pockets lack zippers, they are secured with a flap closure to prevent items from falling out, making them ideal for quick-access storage. The pack is made from lightweight materials and fits snugly against the body, ensuring it won’t bounce or shift during activity. Built-in reflective strips on either side enhance visibility and safety during nighttime workouts or runs.An included length extender is a thoughtful addition, offering extra sizing flexibility for individuals with larger waists or for those who want to wear it over thicker clothing. Its adjustable elastic waistband ensures a secure and comfortable fit, making it perfect for active lifestyles. Whether you’re hitting the gym, heading out for a run, or traveling, this fanny pack delivers convenience and style in one compact package.

        Nice buy

        Love that they have a velcro attachment to make it slightly bigger. Being a powerlifter I don't have a slender waist so that helps a lot.

        Great for Active Phone Carry

        I've been using this running belt during my morning jogs, and I must say, it's a real find! 🏃‍♂️ The three roomy pockets are a game-changer (oops, couldn't resist!) for someone like me who likes to carry both essentials and some extras. The Velcro closure is strong and stays put, even during my most intense runs—no more belt creeping up on me! 😅What really impressed me was the waterproofing; it kept my phone dry through a surprise drizzle, which was a huge relief. The middle pocket with a zipper adds that extra security for valuables. The material is soft and breathable, minimizing any sweat buildup against the skin. Plus, the headphone port is a nice touch for music lovers on the go. 🎶All in all, this belt is a solid choice for anyone who needs hands-free convenience without sacrificing comfort or worrying about their gear while working out. Give it a shot, and you won't be disappointed! 💦🏃‍♀️📱

        Good as a slim money belt

        Wore this on a 11-hour flight and a day of additional travel as a money belt. I opted for this because it was slim, unlike the bulky money belts actually sold under that label. Wore it around my upper torso with a few thousand dollars — was unobtrusive and discrete.It got a little sweaty after several hours. If I had to wear this for several days in a row, I might opt for one of the higher cost ones to see if it is more breathable. But that’s never gonna be my life, and next time I need a money belt, I’ll be happy with this one.
