The fit, warmth, and breathability of this shirt are unmatched! I’ve worn it countless times for hunting-where I have long periods of high impact activity alternating with sitting in temperatures that range from <10-30°F. The zipper helps for high cooling during hiking. I’ve also used it for hiking during travel in the western US. Unfortunately, the zipper pull broke and, while I was able to still use it for a few times after that, it’s now stuck open and I need to buy a new one. I have since purchased the I train it version, which is warmer, and has a smaller fit, (I have M in both.) but I like this version better, with the exception of durability.
I'm new to merino wool and I was initially skeptical at the claim that it keeps you warm during cold weather, doesn't smell, and doesn't hold sweat like cotton. The claims are true. I couldn't believe it. This is my base layer that I wear hiking and backpacking. I have a curvy build, 5'6" 150-175 lbs and it fits nicely. Not too loose not too tight. I believe I purchased the lightweight version. It doesn't hold sweat like cotton but it is a breathable fabric and the sweat dries pretty fast. Worth it!
My favorite top for hiking in cooler weather. I like this as a layer under jackets in colder weather, or on its own for those in-between days.
A good base layer weight. I would buy again
The fabric is much thinner that I expected and the shirt runs a bit small especially as compared to the smartwo t-shirt in the same size which fit perfectly.
