So, today was another experiment in wool, which failed. Put the smart wool base layer on, with a full zip light thermal Craft jersey. No way... I sat around my house itching for 2 hours and changed to a different base and mid layer before going snow shoeing. Then, I put my Vim Hybrid jacket on when we left. It was about 31, but the temperature was going down, it was cloudy, and getting windy. I felt cool until we started climbing the 20+% grade hill for about half a mile. But, no excessive sweating, which is excellent.
Not sure what this means, except that it seems that wearing a wool base layer one day sort of sensitizes my skin and starts some kind of histamine reaction, which is OK if I don't annoy it by wearing wool the next day.
