I have the iphone 6s plus which is large for some of the pockets in pants. I purchased the bra to see how it would work. It fits my phone and does not bounce around when running. They have the clasps which make it easier to get off after a soaking run. Loved this bra so much, I bought 4 more.
I originally bought the granite heather in medium. They were VERY snug. I can wear them but I then read reviews that said you should buy a size up so Ii bought 2 white ones in large. They are almost too big. I guess I need a medium and a half? I don’t know if the mftr is different for the different colors but was just weird. Keep in mind, I still will wear both sizes but wish I could find one that fits perfect.
