Greg/MO will be on in a minute to tell you why Fall Grey will work just as well early as late and he may be right, but it still looks funny!
LOL.
I agree, in the Wolfskin, the white is not as white as on other material. Probably because the material itself starts out darker/different. Same as the brown. I'd imagine that's the same in wool. Don't get me wrong, love the grey but the brown and I have some incredible success both spring and fall through winter.
