Great and really absorbent microfiber sports towel (slightly disturb the zipper)

I bought two of these sports towels. I use this at the moment for a jog. So far, I'm really pleased. The towel is very easy and you can lace around the wrist or around the neck. I am fascinated by the absorbency. Jogging every other day for about 1 hour and am really happy that I have my sports towel here. What bothers me personally is the zipper. I do not have so forcibly take any key or jogging. It would be really great if there was even a version without specialist. I think for my part, that it is just a waste of space.
