After about 2 hours, however much I jogging significant moisture in the inner casing (without rain) and really good fixed is not the phone.
The inset is very high up and not overlaps on the cell phone, so it could theoretically out move up would also definitely not protected from rain.
I've made in the (very narrow) overlap a hole for headphones. This mobile phone is at least somewhat fixed.
Positive is the right long arm strap. I have pretty skinny arms, but most straps are too short ... this is not.
If I had the choice, I would not buy again ...
