I can't deal with waterproofs that make you dripping wet, if pressure washing an ppe is required I had the orange pants from screw fix bout £15 but couldn't deal with the sweaty nuts, bought breathable ones off eBay which are much better
If no ppe required I just hit it head on in me shorts and wellys ....... Ok til ya pull up at home and the wife sees the crap all over ya legs, sends ya right to the garden tap to clean up before allowed in
