As sunscreen probably sufficient, I had to wander bought this hat as a rain hat as he was also advertised, water repellent here would probably have been more correct. He no longer fulfills the rain protection function! I have this hat a few years and so far he has been sufficient in light rain. After exactly a wash not (and subsequent impregnation with iron according to the instructions for updating the Aparatur) now just 2-3 hours Daueregen and the material is limp and absorb water almost, because you can take any cloth hat and impregnating and must not so often wring ............. For the same reasons I have a mammoth Drytech jacket sold because this material just did not fulfill the intended function (unfortunately noticed too late) and also difficult to dry. All möglicheh care instructions have been followed, the result is pathetic for a hat this price range. The company is applying its mammoth DryTech material explicitly trying to wash it regularly for contamination. The two star gets the hat just because before washing worked the imaginary function. It urges the impression on the mammoth, similar Wolfskin, pure lifestyle products raises the market in order to make sales and neglecting the actual functions of these textiles. Too bad the my (already older) Ultimate Hoody Softshell I let nothing come ............ although it probably should there be significant differences in quality.
