SmartWool PhD Running Shirt - Merino Wool, Short Sleeve (For Men)

In an effort to replace most of my clothes with merino wool, these undershirts were a must have. These shirts are super comfortable, don't stink, have a great fit, wick well, and are a joy to wear. As many of my merino wool garments, I hold them to rigorous performance standards. I have been wearing these mostly at night to sleep in, and as a quick morning yoga/excercise before I get my day started. A couple days I wore them as an undershirt to my business casual attire. I have been wearing them for nearly 2 weeks straight, only washing them once when I first got them. They don't smell at all after 2 weeks. Boom! That's the beauty of merino wool.
The fit: I am 5'10" 150 lbs, athletic build with a tall, slim torso. I bought a small size and I think it fits great. The shirt length is shorter than most t-shirts, but it works to my advantage in that I don't have to tuck it in with the collard shirt I would wear over top. It comes down to right on top of my belt line, or the top of my boxers so my belly isn't exposed. The collar is trim enough to not have bacon crinkles, nor does it strangle. The shoulder width is great because the shirt doesn't feel like I'm pulling it apart when flex or swing my arms around. The arm holes are nice too, sometimes small shirts pinch my armpit since the arm-hole is too small for my muscular arm. These don't do that. They are perfect. I would definitively recommend getting this shirt!
