For skiing, solid air!

Exudes strength, I took to ski with, I have no doubt as to what it will protect my phone. Delivered on time, the seller answer very properly and very quickly to the request. A advisor.
Negative point for usb cache, it slightly prevents access to the hatch to access the usb, but it is more accessible than some shells yet much lighter (Neo Hybrid for example)
As against the plastic of the cover to the air not to hold very properly. Nothing too serious for the use I want to do, I will not dive with it anyway.
Protects, shock, dust, snow, but in terms of the mud or immersion in water, we must find better.
