As a runner, I have been looking for a product like this to comfortably run. I tried armbands for my phone, my pockets and fanny packs. the problem with the arm band is, it slides down my arm and adds weight to one side of me making me feel unbalanced. the fanny packs are too bulky and moves around on your hips. I love this belt because it is tight against my hips like the waistband of my pants and the slots on the belt help me easily access my phone in the front . there is also an attachment to clip my keys onto and extra slots around the belt to put money,credit cards, power bars etc. I recommend this product to anyone who exercises, because it makes exercising so much more enjoyable.
