The 100% wool, but stretch and breath ability is amazing. Look forward to more shirts becoming available.
The shirts I bought are awesome! Superior quality!
I love this merino tee - it's breathable and lightweight, which is great for warm weather, spring & summer activities. It's also super soft and nice to wear, plus resists odor over the course of a multi-day excursion (which is important!). I've been wearing it on multi-day biking, camping and spring ski missions and will definitely continue to use it on my adventures and for casual day to day.
Bought as a base layer for refereeing spring soccer in Alaska. Only worn once so far while x-country skiing as a test run. Seems to work great at regulating temperature while exercising. I have found merino wool shirts to be one of the best base layers for strenuous exercise as they keep me warm even after getting damp from sweat, and this one works well.
My favorite shirts. Warm in the cold, cool in the heat. Soft, comfortable, great fit.
