Review on 🏃 Versatile Running Belt for Women and Men - Waist Pack with Phone Holder for Running, Hiking, Traveling, and Cycling - Runners Fanny Pack and Money Pouch Case - Fits All Phones (Includes Sports Wristband) by Chris Endricko

I carry a standard sized water bottle in this bag and it really fits and doesn't even bother my phone in it. I only carry my key fob with me when I run, so it fits in there too. All in all I really only have 3 things in it and all 3 things fit and I still have some space left. Despite all these things inside, the bag stays attached to my waist. There's a slight stretch, but not so much that it falls off my waist. The strap is fully adjustable and I adjusted it to its tightest to make sure it wasn't. Even if worn while running or walking, it will not come off. Once turned on, that's it, no movement or self-adjustment. The great thing about this belt is that it is washable! I just don't dry it but despite all the sweat it doesn't stink too much but I love being able to wash it and it looks new again.
