Nix for bodybuilders upper arms but otherwise value for recommendation!

Good and secure storage while running seems assured here and serving ports are open and gutberreichbar, never should be. Better usability by the Displaschutz would be nice, but I think the product is technically difficult to implement. The only real drawback in my opinion is the quite short drawstring. I am now not the bodybuilder, but already have a compression arm when I wear that thing on the sweater (and the supposed times occur in winter). Nevertheless, I think the thing just in terms of the price really good!
