Coolmax itches me. Not a lot, but enough to be really annoying, especially at seams.
As a result, I've worn my Specialized superduper coolmax wicking sweat away shirt once, and use soft cotton tshirts in the meantime, which gather my huge amounts of sweat.
Two more fabric technologies have caught my eye in my googling.
The company Castelli apparently has stuff that is similar to coolmax, but more comfortable, and then there is this wool (wool?!?!) product that's is supposed to be completely non itchy, called Merino wool.
Anyone got experience of either?
