Great daily all-around trail shirt.
Really like Wuru's Nuyarn lightweight hoodie! Put it to the test wearing it almost every day for five weeks on the trail. Temps were 40s to 70s and it always felt comfortable hiking. I washed and rinsed it along the way but never noticed it smelling. Looked great every day -- and still does. I also love the Moss Green color.
I'm 6' 170# and the large is a tiny bit looser and longer in the arms than I like, but comfortable and allows room underneath for a base layer. (I dont' know if the long sleeve tech shirt base layer is sized the same, but I found that a medium in the base layer was OK, but a little tighter than I would want in a top layer like the hoodie, so I was probably better off getting the large hoodie.)
If you're trying to pack light and just use this one shirt, I found it handled almost any condition well, but I still wanted a jacket in cold winds and maybe a base layer if standing around in cold weather. Also, a light wool beanie or balaclava is nice under it in cold weather because the hood is pretty loose and doesn't add much warmth, which is as it should be for a sun hoodie. For full sun protection during the middle of the day I also added either a visor or a trail umbrella, because a hood can't provide full face coverage.
