This question has been driving me crazy for the past couple of weeks. What is the difference between Polypro and Polyester?
I read quite often that Polypro base layers stink. I have a "polyester" base layer that (I think) stinks in what seems like 2 minutes after I put it on. So what gives?
While we are on the subject, what is your favorite base layer? Cool weather? Warm weather?
On a thru-hike, should I take 1, or 2 shirts? I have a separate "top" I use for sleeping.
