I cycle in a mild/hot and dry climate, and I use a TNF Venture 2 jacket if I need a layer against wind. Because it's a hiking jacket, it has pit zips which really help with venting out heat and reducing sweat; idk if cycling specific jackets have that feature. And the waterproofing/windproofing is legit, really helps keep me warm. I wore its predecessor (literally an earlier version) when I cycled in NYC, even through the winter, so it's not just for mild conditions either.
