I think the polar buff is the one that is fluffy. That one is the warmest--really, it's too warm for temps above 25 degrees or thereabouts, so I'd prefer the thermal one (just regular lightweight polartec).

CA--I found the best selection at the Buff website. Can't remember the website address (buff-usa.com or something like that). Best to Google it first or you might end up bringing up a porn site.

Just FYI--I'm hoping TE decides to do Buffs in the TE logo or even just stocking them in other designs. I asked about it awhile back, but at that time, TE was going to hold off on seeing how popular Buffs would become. :-) fingers crossed that this thread will help push them into doing some up.
