Great shirts!

I have a pair of these shirts (along with a long sleeve and zip-up) now and they are great if you are willing to take on the slightly higher maintenance requirements. I am 6' and about 170lbs (with a shortish torso) and the medium fits me great. I wear it for everything, layering under warmer gear, by itself casually and on long runs and it works everywhere. Soft and no scratching, doesn't stink even after a couple runs back to back without washing.

Speaking of washing, I wash it cold and make sure to give it a little stretch before laying out on the drying rack and it has not shrunk on me. Get yourself one (or a couple and don't look back.)

I really love that these are made in US and I love supporting a company local to Salt Lake!

One of my favourite garments

Good fit, and a nice feel. Feels even better than regular merino.

If I Gotta Wear a Shirt, This is the Shirt

This is the best dang shirt ever. I've become a wool-shirt snob. And this is the best one I've owned.
I use it at the gym and to run in. Doesn't get heavy with sweat. Very light weight feel. Odor free. Can wear multiple days in a row with now stink.
Also looks great for casual wear.
Buy one and try it. You won't regret it.

Comfort - Amazing for Ultra Running

Perfect for Ultra running; the only shirts I have worn that does not chafe nipples after 25+ miles when not wearing a vest. Bravo Matt and team
