Warm and soft

I love this shirt. It is fitted enough to be a base layer but not too tight. The fabric is warm and soft. I am very short and many other brands I’ve tried have sleeves that are far too long. These cover my hands if I want but are not so long that I have a bunch of bunched up material at my wrists. I really love this shirt. I’ve been wearing my long sleeve multiple times a week as the temps have dropped the past couple weeks. It has been great for long periods outside in the snow.

Great shirt!

The fabric is super soft and the fit is nice. Not baggy but also not tight. I really like this shirt. It is a very light weight fabric so I hope to try a little heavier weight for winter.

Love this shirt!

I absolutely love this shirt, I use it as a base layer for running. I wore this with a vest and light jacket and was plenty warm when I went out to run when it was around 30 degrees and super windy. And even with the wind blowing hard, I was perfectly warm the entire time despite sweating. Previously I had been wearing at least a couple other layers and I would freeze when the wind blew. It washed well and dried overnight laying on top of my dryer. The fabric is very soft and stretchy, I love the length as well, I have a long torso and frequently find shirts are too short. This was plenty long enough and didn’t ride up at all. I can’t wait for more colors to come back in stock so I can get some more.

The shirt is soft and comfortable and the Flintstone is a pretty grayish blue. The material truly does not absorb body odor. The length of this shirt, however, is not as long as the previous version. The tail does not cover my bottom like the previous style in the same size. Also, the seam on one of the arms is crooked so I have to pull at the sleeve to keep it straight.

Soft and lightweight

I liked this line of merino wool. I know "they" say no itch but I do. This is the first that doesn't . Usually I can wear merino wool only an hour or less before I have to take the clothing off, but WURU I can wear all day. It is lightweight and soft.
