I bought this shirt as an additional layer for my cotton tee shirts. It is perfect. I like the wool blend; warm and breathes well. The outside is tough; the inside soft. It is perfect for around the house if you keep the house cool, and works well outside as an inner layer.
My mother in law got my husband this shirt for Christmas last year and he really like it so I got him 3 more for his birthday this year he said that they are the warmest t-shirt that he ever had he does a lot of hunting.
This is one great shirt. The 2 layer wool and cotton really keeps you warm. It's nice and soft, and does not itch. I also liked the sleave detail, so it can be cuffed if need be.
The river driver shirt is one of my favorites of all time. Got mine last Christmas. I found it to be perfect for staying warm and dry while surf fishing this autumn. It is also great as an underlayer for colder days. I definitely am hoping to get a second one for Christmas this year!
