Have you tried merino wool apparel for either teaching or your own workouts?

I have a lot of merino wool products, from “smart Wool” socks in different lengths and thicknesses to merino wool tops and bottoms as a first layer undr fleece. Also gloves and mittens, but of course I live in Wisconsin, Where we only have 3 months of bad sledding. Plus most of my personal workouts are done outside in parks or on Ice Age Trail!
