I’ve worn my Brnyje for two field trainings (I was mostly standing around) under a fleece layer and my Carhartt and it kept me comfortable, not too hot which was another worry. My only minor complaint is the torso length with the XS (based on my measurements) but I have kind of a long torso for a female, but I tuck it in and it works just fine. I wore it this morning under some UA heat wear for a 5 mile run to see how it does with physical activity/sweating, but so far worn it 4-5 times and it doesn’t smell.
