Love it, only issue so far is I struggle a bit with the water bottle but I’m sure I’ll get used to it with some more time.

Great running belt. Great material. Better than others that i have bought in the past as this one is elastic and stretch for comfort.

Just finished my first half marathon 6/28 the belt and flask helped me so much throughout this race. I even bought a second belt for my fiancé and she absolutely loved it for this race!

I would recommend this to anyone.

Great piece of gear to carry my phone and gels for those long runs. I’ve tried a few different belts on the market and this heads and shoulders above the rest. True to advertising the Endorphin Belt stays tight and doesn’t bounce or sag. This is exactly what I’ve needed to train up for my IRONMAN triathlons and marathons. Great quality and worth every penny.

Excellent! I don’t really use the flask but the belt itself is fantastic! No bouncing or uncomfortableness. Holds everything I need. I use a regular water bottle and fits perfect. I highly recommend.

I wrote a review in late April 2026. I had an issue (1) losing gels in the loops and (2) zipper broke off.

I’ve ran 250 miles the last two months. No problems with gels using the loops they stay in extremely well. It does require moving the gel around in the packet however once it place it stays well. Great storage space for phone, gels, soft water flask. Probably could carry more than I’ve put in. Zipper has stood up well, I’ve also been much more gentle with opening and closing too. Belt adjusts great - easy to do on the run.

Great product guys!

Awesome , exactly how they describe on social media

Exaclty as described. Love this product.

The Endorphin Belt works exactly as described. There is no bounce, hold everything I need and is truly waterproof!

Getting back into running andreally like to have my phone on me for safety and for a little music. Phone fits in the large pouch perfectly. The smaller pocket has plenty of space for other items. Stays in place, no rubbing great product. I’ve been using it a few weeks so I don’t know what the longevity is but it looks like it’s well-made.

I used a much simpler version of a running belt for my phone but needed a massive upgrade for the Texas heat! Have been using the Endorphin Belt for 3 weeks now and it has been a game changer. Super comfortable and doesn't bounce. stays snug against the body.

This belt makes use of all available space. I had a previous belt that bounced like crazy and could only hold either my Iphone or collapsible water bottle. I have an iPhone 15 pro max and this belt fits that, the endorphin collapsible water bottle, key fob, and gels. It is perfect on all my runs (easy/tempo/long). I tighten it during faster runs and it does not get in the way. Another huge plus this belt has compared to my previous one is it’s waterproof front pocket for key fob and smart phone. Also their water bottle is the best collapsible one I have found. No weird plastic taste.

Enjoy this belt so far. I've competed in a very tough hill course with it. No bounce and everything stayed in place.

I’m thinner and I have it adjusted to its smallest size. It has minimal to no bounce depending on how many ounces I’m carrying.

Love the fit , really happy about the purchase!
