I really don’t wear cycling jackets. I have the showers pass which does not convert to vest.

What I normally do is combine arm skins and a cycling vest in various combinations weather depending. The main advantage is you get warmed up and arm skins go off or pushed down the arm. Suddenly cold or in shade? Skins go back up. Skins up and vest unzipped. Endless fun and variations depending on you and the weather

I have lighter weight and heavier vests. Regular arm skins and a pair or two smart wool.
