Following on the enormous success of the original HiFlex trousers, Stihl have now further enhanced the range with a Class 2 version.  This means that these trousers have been tested on an approved test rig with a chain running at 24 meteres per second (the original Class1 style were tested to 20 meters per second), to give a higher level of protection.  Otherwise the features are the same as the 011333 HiFlex style, with only a slight weight increase for the extra protection.  Please contact us by 'phone / email if you are interested in purchasing this item.
