Prime Shirt for Mountain Running

Loved this shirt so much I bought it twice! The merino blend regulates temperature incredibly well which makes it perfect for alpine starts or long, cool days in the mountains. The fit, as another review mentioned, is a little long which I didn't mind, but it's certainly not excessively long. Through the chest and torso, it fits slim but not snug and the sleeves are a bit on the short side. Additionally, the fabric can feel a little clingy out of the bag but with a few wears and washes, the shirt softens up substantially. All in all, it's a great piece! I would wear this shirt on every run if I could - and the merino makes it tempting - but I'll settle for 2-3 times per week. Highly recommend.

Too long. It's kinda like wearing a dress. For comparison it's about 3 inches longer than athletic shirts by the north face or Patagonia, but if you sweat a lot it hangs lower and lower until it looks like you're not wearing shorts. Otherwise its quite slim fitting. Excessive static buildup makes it really clingy and uncomfortable .

Softest. Shirt. Ever.

This is the softest shirt ever. Incredibly light, too. Definitely warmer than the equivalent weight synthetic knit/mesh fabric, but probably about the same temp as a synthetic non-mesh shirt (e.g. capilene). Quite comfortable even when sweaty with no discernible odor after a few sweaty wears. Very quick drying. For me, it's perfect for either lower-output activities above 65˚ or higher output below that. Fit is a comfortable slim fit. At 5'10, 180# athletic build, L is comfortable and not skin tight, but also not too long. M would probably work because of stretch, but would be very form fitting.
