This is definitely the most comfortable of its kind. It’s flimsy, though, the material will stretch out. Your phone can fit right inside with the cover on, though, which is handy. I love this armband. It will fits your 4s with Otterbox defender case. The velcro is strong as is the stitching, and it has a small pocket on the back – just be enough for a key or credit card. This band can fits for customer who have very small arm. It’s hard to navigate through the phone through the plastic cover, so I’d advise getting your music and running apps set up before you insert the phone. The material stays tight around arm and doesn’t slide when gets wet with sweat. Wireless earbuds can worked well with this, so you don’t have to worry about plugging something in to the phone while in the armband case. I would definitely recommend this for other runners.
