Should the base layer of polypropylene be skin tight or is it just as effective if worn a little loose.?

If your shirt is a little loose,you'll be fine.Your mid layer will hold your base layer down.Tighter fitting will always keep a more uniform dead air space and will wick a little faster,but I would not get rid of a shirt that is a little loose.

I'm in the process of replacing most of my base layers with Merino wool. Doesn't take up or hold odors like the synthetics do.

I'm a fan of UnderArmour and used a "compressed" (skin tight) Winter base layer on my thru-hike. Even though very effective, I found it a bit restrictive (uncomfortable) after hiking in it all day. I've since gone to a "fitted" (looser fitting) Winter base layer and found it just as effective and more comfortable after long wear. For warmer weather I prefer the looser fitting. For me it's a matter of comfort during 10 hours of hiking.

Merino wool is a little more confortable than polypro. but is heavier and takes longer to dry out. I have found using wind gear instead of long underware during a traditional 3 season thru hike to be lighter and a bit more versitaile. :pimp
