Great Mid-Layer
I used this as a mid layer on a recent climb of Mt. Washington. It turns out it was my outer layer almost to the summit. This was so warm I had to take off my shell. I would put on my shell for rest breaks. It is very breathable and moisture wicking. I cannot believe how this performed. I would buy another but that won't be for awhile. This is a very durable layer. I am 6'3" tall and 210 lbs. I ordered an XXL so I could wear it over a layer and to allow for shrinkage just in case. I love the fit. It is very comfortable. You get what you pay for and this purchase was well worth it!

great winter weather garment
This truly is one of the most comfortable, soft wool products I've ever owned. I am a snowboarder and love to fly fish in the winter in Utah, so this is the perfect shirt for me. I ordered an XL because I have wide shoulders and long arms - I was concerned that the body would be cumbersome, but instead find the fit perfect for me (I am 5'11", 190lbs).

A Good Addition
I am the ultimate fan of Merino Wool so purchasing this item was a an easy call. I was not familiar with the Ice Breaker brand but am very impressed with the quality of the item. The feel, look, comfort and warmth is terrific as advertised - jury is out on durability since I haven't had the shirt long enough. Now the big question, is it a shirt or a sweater? either way it is a great mid-layer item and I'm very glad it's in my closet. I will look for Ice Breaker items going forward. I will say it fits a little small so I'm glad I bought the XL. I am right on the boarder between L/XL and this item in a Lg would never have fit me.
