If there is a chance of rain before I gear up, I wear 100% GORETEX jacket, pants, boots, gloves. On non-summer trips, I only wear GORTEX gear. My mesh gear and backup rain gear are for local summer runs. I stay dry and the GORTEX breathes. Rainsuits get VERY steamy and you have to guess when to wear and when remove between showers. Pulling over to switch can be hazardous and slows progress.
I was raised in the UK, and long before genuine Goretex type gear was available. Everyone had a Barry Sheene (RIP) endorsed Rukka over suit, Rukka over mitts and Derri boots. If it was going to rain, especially in winter, it was likely going to be for days on end.
I have a BMW textile adventure jacket from way back when which I admit works well, and it even has a secondary waterproof liner. The pants, however, were never quite waterproof. I returned them twice, but each pair suffered from nasty wet crotch syndrome.
So, I’ve settled on the over suit type of rain gear and sure, sometimes it a bit inconvenient to put on and take off, but I’m lucky I live out in the usually low humidity desert so the steamy effect is usually gone a few minutes after the rain stops.
Being you can see for many miles and therefore predict as to when the rain is coming, timing when you need rain gear is usually fairly easy. For most of the year, it doesn’t rain much either.
It must be my upbringing, but I quite like riding in the rain. That feeling of it being all wet and nasty, yet you are all bundled up and bone dry, is somehow very satisfying. I know, I’m weird.
