Great for me!

This type of layer is why I love merino. It's fairly light weight for what it is at 260gm, but the warmth you get out of it is insane. Throw in the zip pockets, and it's so versatile as a midlayer that I need two of them. Awesome in the backcountry, on a run, or around home/work. Thumb holes are in the perfect spot and the hood is just the right size for not having drawstrings. I am 6'1" about 175lb, and the large is perfect for me...my chest is probably around 41."
