I use this sport mat (black) now for several weeks and have to say, just great! Does not slide around on the floor, the top is a tacky feel due to the grooves. Welding can be wiped off easily. After use simply roll again and stowed away. The holding rubber is designed so that you can throw the mat sometimes on the shoulder and where (z. B. the studio or on the sports field) can take. Would I buy it again, when the time comes. ^^
