A very breathable "torso part", the shirt is comfortable to wear under a protective vest throughout the shift without having to sand or rub.
5/5 shirt. Was in daily work use 1.5v after which there were small holes in the back that did not start to enlarge. I highly recommend. The only downside I came up with was the long sleeves that stayed in place with good velcro fastenings at the wrist.
Pleasant feeling on top. Hem long enough. Sleeve volume fair for such cords.
Sufficiently long hem, a cut that allows movement and a comfortable top. Not yet tested on the "operation" shirt on, but based on preconceived expectations, it would seem to work.
