When it's 104°, I can tell the difference between a Rapha Pro Team Flyweight and my other jerseys. Evaporative cooling can be felt. It's really remarkable.
Also, +1 on the chamois.
Elastic Interface pads are top shelf and not cheap. The
Space 2 chamois in my 7Mesh bibs is like riding in your rich uncle's Cadillac.
