The Airex "Fitline 180" Fitness Mat is a very nice fitness mat. I had no issues or concerns relative to quality, construction, finish, etc. The "Charcoal" color is nondescript and will not stand out, which is good for a lot of guys. The 23.5" width is fairly standard, and the 3.3lb weight is manageable. As a man, the 71" length was very good for me as many other mats are simply too short.In terms of thickness, the 0.4" is fine for many yoga poses and floor exercises. See full review
