V Valanch blue shirt with great workmanship, material, and design at a fair price
The V Valanch blue shirt has a nice collar and great workmanship for a reasonable price. I have a few in different colors and they don't advertise on the shirt (Not for label snobs) so you will look great but not whatever a little logo does for you. These seem as durable as my RL, 3 stripe, and UA golf shirts which are great but the collar isn't as shaped as the V Valanch shirt. Recommend.

I bought three!
Great fit and great material. I bought three for work.
The German design is preferable to the standard US polo shirt 👕
