Excellent quality hats! Had it out in plenty of rain and its 100% waterproof, you also don't overheat so it breaths really well. Have worn it pushing through soaking wet scrub and undergrowth in the rain, when pushing through head first with this hat on its remained fully waterproof and kept the rain / wet off my head and face. Both of which remained nice and dry despite the harsh weather.
Awesome hats, 100% recommended!
