I'm no scientist, but it just seems to work for me (33 - 40°C and humid). I spent years not using them as assumed the extra layer would just make things warmer. I like having the option of unzipping my jersey and letting air in through the mesh without getting semi-naked. Only use light sleeveless ones (from Albion).
