That would be my option, they wick away sweat so well that they never feel wet. It is a very versatile base layer that will work through the seasons when layering is done right. They also wear really well – I haven't got damage in any of mine after lots of use.
I wouldn't say they make you feel cooler, they make you feel fresher as you are not dripping. I prefer them paired with Pro Team jerseys but they work just as well with sports wool. I used to swear by the merino base layers until I gave these a go, now the merino is for winter only.
