Review on 🏃 SOLMOSAIC Waterproof Running Belt Waist Pack - Fits iPhone X, 8 Plus - Fanny Pack for Outdoor Sports, Hiking, and Fitness - Pockets Belt for Men and Women During Exercise by Dwayne Pore

I didn't like it at all - two reasons, size and function. I have an iPhone 8+ and can squeeze it onto the belt, but it's so tight there that it's impossible to quickly insert and remove - you practically have to remove the belt. Also, the belt has no stretch or stretch material so while you can tighten it around your waist I found it would not stay upright at all - it kept slipping off so I pulled at the 8k race, where I used it, all the time. Lifting and tightening the straps is not good. I returned it. It's well made and appears to be waterproof, but I just find it poorly designed and not very functional for running.
