Before it is too late. Patagonia’s having a crazy (60%+ off) sale on base layers, most importantly on their very nice and normally very pricey Wool 2.
I’ve had Wool 2 t-shirt since spring. A bit on the fragile side (don’t go climbing off widths in it), but super soft, amazingly warm for it’s heft, a great moisture transport layer, and absolutely the most stink resistant garment I own. I wore it all during Le Parcour, and while I stunk, it didn’t. I still don’t understand how that works.
Wool isn’t (yet) the silver bullet of base layers. The thicker stuff dries too slowly, and the thinner stuff is too fragile. I’m begging Patagonia or Smartwool to jump on the bandwagon with Mammut and come out with a wool/poly blend fabric in the next 18 months that will take over the world. Of my armpits, at least.
