To all like-minded "broader" upper arms types like me: this iPhone 5 support has more setting options. Overly said you could tie this thing also to the thigh, because you have to put the Velcro by 2 eyelets not mandatory.
All previous posted by Vorrezensenten concerns over the upper arms are unfounded, because this belt also holds when only simple "Verklettung".
while the price in the basement you can strike without hesitation.
The thing slip anyway even after 1 hour of running not, but it feels quite damp. Is probably the Neoprene.
