More comfortable than some competitors
I’ve become a repeat customer for this belt and converted over from another popular brand. I find that this particular belt is a little bigger, both in terms of the pocket and the width of the pouch when empty. This pouch is a little less elastic, but also seems to last a little longer before wearing out. I typically use the belt for running, typically about 20 to 35 miles per week. It has a lot of room to tighten down, even as it gets older and starts to stretch out. Unlike the brand I used to use, the strap is wider, which makes it a little more comfortable and it doesn’t have any rubbing points that cause skin breakdown or hot spots on my waste. The other version I used to use had fastening points that would rub against my skin and result in chronic sore spots. It works well resting either in the front or on my lower back. The water resistance seems to be very adequate for runs where I get soaking wet and for light rain, but I haven’t really been able to asses its effectiveness during a torrential downpour. Plenty of room an iphone 11 and a few other small items, and seems like it would fit a much larger smart phone as well, or a passport. Definitely glad I switched to this

Excellent for the essentials
Most of the reviews were by a younger geographic. I am older, 60+, who enjoys an extended daily walking routine. This belt is exactly what I was looking for. It’s comfortable, light weight and holds everything I need without being bulky. I will say that it is a little tight holding my iPhone 16, but it did fit nicely. This might get easier the more I use it, but I was able to hold my phone, key fob and ID without any issues. I would highly recommend and am very happy with the purchase.

Great product and AMAZING warranty support! RECOMMEND!!!
I purchased this in Dec 2020 and use it 2-3 times per week for walking, running and roller blading. It holds my iPhone 12 perfectly, along with some lip balm, credit card, ID, cash and other small items. The zipper has a sealing edge that keeps water out, like rain and sweat (but not sure if it would work completely submerged). But the number 1 reason they are 5 stars for me is the incredible customer support. In Dec. 2022, almost exactly 2 years after my original purchase, the zipper separated and the only way to repair it would have been to slice the end of the zipper and manually insert it. I didn’t want to do this because I would have to realign the teeth every time I wore it. I looked online for a new one and my husband said “maybe it has a warranty”. I checked, and IT DID! A TWO YEAR WARRANTY!! I was just under the wire and contacted them and they sent me a brand new one immediately! I was pleased and amazed. 5 stars all the way 🙂

It’s made from high-quality materials that are not only durable but also comfortable against the skin. I appreciate the attention to detail in the stitching and the overall craftsmanship.One of the standout features is its ability to securely hold my phone. It fits my device snugly, ensuring it won’t bounce or slip out during my runs. The zippered pocket is just the right size for my phone, keys, and a small wallet, making it incredibly versatile.The adjustable strap is another plus, allowing me to find the perfect fit. Whether I’m wearing it around my waist or hips, it stays in place without any discomfort. The buckle is easy to use and provides extra security.During my runs, I often forget I’m even wearing this belt.

Perfect size! Fits all the necessities! Very comfortable!!
I worked with this brand for photos of the running belt, and loved the product so much HAD to leave a honest review!!! Loved this running belt!!! This bag is super lightweight, but durable and fits all you need while running/walking: phone, keys, money/credit cards, chapstick, ear buds. Love that it is reflective, giving you better visibility for people driving on the road (if you’re walking/running by a road). On the backside it has little “grippers” so the belt does not fall down while running. The straps are adjustable and veryyyy stretchy, so it really creates a good fit without being too tight or too loose! Very comfortable!!! Highly recommend this product!

Great value and stays sturdy while running
I bought this running belt in April of 2023 and have ran about 400 miles with it. The first month I had it the zipper actually “broke” but I was able to get it back in place after a bit and it hasn’t broke since. This belt has enough room for my iphone and car keys, I have fit 2 phones in it before but it is tight. It does not bounce around on me and stays very sturdy. I love it a lot and am glad I gave it a chance despite some of the bad reviews.
