hikermor, we've gone to nearly 100% non-cotton for our outdoor activities, we have lots of the under-armor type base layers, synthetic undies, and fleece tops. We'll also have our boy scout and other synthetic shorts to wear. I'm hoping the april weather will cooperate, if it doesn't we'll both have to rely on our 60/40 ripstop blend pants (i.e. if it's too cold for shorts). Not optimal, but best we've come up with so far (don't ask about the removable leg portion of the boy scout shorts, lets just say DW is NOT the seamstress she thought she was lol)
