Top for backpacking daytime warm/hot weather:
150-ish gms, wool, 1/2 zip (1/4 ok), thumbholes, collared. I’m older and need sun protection at altitude and I like the way thumb-holed covers the back of my hands (prefer it to sunscreen).
I can’t seem to find this combination of features. I currently use an REI product that is perfect except that it’s polyester; thought I’d try wool if it’s possible.
Thanks!
