I really wished I could give this a 5 star but it clearly said on a card on the inside window that phone size 5.5 would fit. I have an iPhone 7 Plus with a bumper case. My phone will not fit very well as the pocket will not allow it to close. All I needed was maybe a 1/2"-3/4" more wider, so I could utilize the pocket. I really wanted this to work out. I love the elastic belt, the most comfortable one I've worn. You're probably wondering how I wore it if my phone didn't fit. I cut the pocket out of it and my phone fits now almost perfectly. So I use it to cut grass and protect my phone from dirt and flying dust particles. So all is not lost for me. I hope they will make one specifically for an iPhone 7 plus with the case protector on it. That would be wonderful to get one for a cleaner activity like walking, riding my bike, etc.
