I ordered the Briele for protection for working with the chain. Material and fit are good, because there is from my side nothing to complain about. However, if you perform strenuous work or prone to sweating fog up the glasses from the inside in no time, can be bad "wipe dry" and can be used only conditionally. "Non-ventilated" stands, the Note should be taken seriously in any case. Price / quality in my opinion in Orednung.
