I was allowed to test the track by Avantree Pouch. The track Pouch is a training strap, stable, well-made, and to take away from smartphone, smart card, some loose change and keys intended .For these things is also the place in this small pocket vorgesehen.Man it can on the upper arm with the approximately 34 cm long Velcro befestigen.Wer can have it, it may also attach to the Wade .For me it was nothing but it slipped with me always down .At the upper arm, it was comfortable to wear .There bothered me in any movement. The track Pouch is equipped with a transparent cover for the phone .Unfortunately I find the film a little too thick, I could only use my phone with difficulty. A small opening for the passage of Kopfhörerkabel.für is located at the bag my phone was this opening to the wrong side of the cable .I should have resulted in the pocket on the phone long to connect it to .Everything in all, I think the track Pouch OK .It does not impede me while running, biking, weight training or inline skates. All that is in Track Pouch is geschützt.Ich've certainly break the body and nothing can fall, and with sweat and moisture. What should also be mentioned, however, see the subjects in the picture bigger as they are. I can recommend it with a clear conscience and have it already getan.Für me it has become my constant companion sports.
