I ordered the upper arm sleeve to finally drift back sport. Namely, it was necessary for a Fitneskonzept consisting of Smart Band (ie an Active Tracker, which is available from various manufacturers) with which you get given the steps and calories burned and can be read directly on the smartphone via app, I Smartphone not wanted rumschleudern in your pocket, so I needed this arm sleeve and it worked as planned.
The smartphone can be ind he cover securely stow and secure the cover securely on the upper arm, so that it does not slip or similar
Sports Outdoor works really well and I am also very confident of the quality shell, considering how little it costs.
All in all, highly recommended, even if for example only the iPhone or iPod has it, he is always tucked safely with this case and can not fall out or get lost. Even a small key is still space in the upper arm sleeve.
