I’m genuinely intrigued (rather than being a nob about it). When do you wear waterproof trousers and do they not end up feeling like a sauna? Even in winter I’ll wear tights but never waterproofs, but that is just riding rather than commuting.
But even if this is commute, are they not sopping wet when you put them on to go home?
I’ve found them useful at times. One time did near enough 130 miles in relatively hot spring weather (between downpours) at a decently hard pace. Turned out not to be the best choice as the weather was WAY better than forecast. Only slightly damp by the end, but nicely comfortable. And that’s the thing. As damp as it gets in there, it’s still drier than when it rains. Yes, you tend to dry when the rain stops in normal gear….but that’s when the waterproofs are useful, when it doesn’t look like the rain is going to stop. It offers you that control. You know what you’re getting with them. And personally I don’t find them bad at all.
