Especially when it's hot... wool wicks amazingly well, and doesn't stink. You can wear the same one for days.
(This is also the key to wool garment longevity... just don't wash 'em very often. They don't need it and it's not good for them.)

I have a few merino t-shirts from Unbound Merino that are a soft, light weight (190gr/sm) that I wear most of the year (non-cycling), and particularly when traveling. I've gone a week straight wearing the same one every day & they never start to smell. If needed, I can hand wash in a hotel sink and the shirt is dry by the AM. I do wear them cycling sometimes, too, but the looser, 't-shirt' cut and length isn't ideal (and considering they're made in China, they ain't cheap at $75 ea...).
I totally agree that lightweight merino is ideal for warm-weather riding. I may get hot & sweaty on a big, slow climb on a hot, sunny day, but make it over the top and start descending and it wicks and dries amazingly fast.
