This is turning into one of my all-time favourite shirts. Great fit and great quality, even after washing it. Icebreaker rocks! Of course the wool is good in hot and cooler weather, even keeping you warm if it’s wet, not smelling for ages, and just all around the good stuff. Whether you are wearing it professionally around the city or going fast in the mountains, icebreaker is a good cross-sport piece of clothing, especially as a base layer or mid layer with this piece.
