I've been having more and more problems wearing wool. Even 17.5 merino. Yesterday I wore my Kate after coming home from hiking, taking a nice shower, and settling down to relax. I was itching after a couple of hours and this morning my arms are bright red. Wearing my Smart Wool ski socks is also bothering my legs.
Since I am going x country skiing up in the Northeast Kingdom in 10 days, I need to get this to settle down. It's a place where wool is mandatory!
