“Heh heh heh. <span style=”line-height: 1.8;”>Is it the gear which is being tested, or the tester?”</span>
Bit of both in Scotland Roger! I think there’s a masochistic streak in those of us who love the hills, whatever the weather. But talking gear, it definitely means that clothing and shelters need to be up to the conditions – so anyone who spends time outdoors becomes their own ‘extreme weather tester’, because one just can’t avoid very strong wind, persistent heavy rain. Winter and Spring bring deep snow and ice on the hills. It also means that while lighter weight shelters and clothing etc are definitely the order of the day, ‘extreme weather testing’ has shown not all of lightweight gear is up to the job. Rainwear, mentioned by the OP is a good example. A lot of fanstastic single or double skin UL rain shells just wet out too quickly in heavy persistant rain, which is a hypothermia risk.
And there’s a reason Trailstars are still a favourite here!
However there’s a great ‘just get out there and do it’ sort of attitude, which is less about the gear and more about enjoying oneself whatever the weather – aided by a flask of Laphroaig 18 year old of course (helps with effective gear testing). In horrible weather you find plenty of Brits on the hills in who obviously haven’t spent a huge amount of money and their gear isn’t particularly light or even belonging to this century necessarily, but they know how to enjoy themselves – they’ll pass you and say, “lovely day for it!”
