It's pricey, but I love this thing. The 260 is deceptive. It looks like a baseball shirt and feels a bit heavy. When you first put it on, you think, "I don't think this is all that warm." But it will prove you wrong. The fit is excellent and the raglan sleeves are my favorite design aspect.
But as a photojournalist, I was out shooting a family story on the rim of Canyon de Chelly in 20 degree sleet with a punishing wind and it got me through and never felt soaked. I bought two more after that. It even works great for Nordic skiing baselayer. Unlike every single Smartwool shirt I have, there have been ZERO seam unravels. The stitching is really top notch.
For cleaning, I cold wash gentle cycle and hang dry on my pull up bar.
