Over 2 years with this helmet, with a large use (almost 6 hours per day in a workshop), and really satisfied. Really solid (former intra Creative has less than a year), the same hold on.

Those who prefer to put 100 in your way past the helmet, the other is this one for you! The little things: a lack of insulation, and a lack of bass ...
