My goodness, I've been pleasantly awestruck at reading about these nigh-unbelievable qualities of merino wool! "Magical" really seems to describe its abilities. I'd learned of wool's great thermal and moisture-wicking properties through these forums but didn't know about the ridiculous resistance to odor. When looking into merino wool base layers, I was planning on eventually getting quite a few of the same type to switch throughout the week like I do with T-shirts. Now it looks to me like I can just wear one for the whole week then wash it once. Now the higher prices on merino wool base layers don't seem bad, considering I'll probably do fine with just one! So as long as I follow the fabric's care instructions, it should be fine to wear for a week straight and wash it once, right?
