I mix and Match to suit the weather.
I commute daily – including weather like today and floods.
Regular gear this time of year is Decathlon running tights and a winter longsleeve running top.
I always have my Howies Dyfi Enduro in the bottom of the bag in case of sudden rain.
When it’s obviously going to chuck down and blast like today, I have a bright orange Endura Nightvision that I lost the REMOVABLE light for. I open the two side vents and it isn’t boil in the bag when worn with a summer running vest.
Mountainbiking, I use Montane etc for jackets. Bike specific stuff us frequently overpriced rubbish by comparison to actual alpine kit.
I’m unclear what OP’s problem is, unless they wish to underline that the majority.of commuter specific riding gear is junk, which isn’t a bad shout but it’s only the first step to discovering that it’s OK to wear non bike stuff…
