Is there efficient rain gear for both for rural (highlands) and urban
Yep. A waterproof and wind proof jacket. Preferably breathable. It’s an area in which we’re still up there with the world leaders!
Although, not to be hypocritical, I have recently purchased a sort of ‘halfway house’ in the Paramo Velez Adventure Light Smock which errs on the side of ‘jacket’, but has the ‘pull over’ properties of a poncho. Haven’t used it in anger yet, but the brand is good. The asking price may be a bit rich for your blood though and it might be a bit heavy duty for June (I’d have switched to one of my lighter jackets by then, personally - too much ‘boil in the bag’ if you get my drift!).
