The upper has lost elasticity and now sags and no longer functions effectively. Only 2 months. Very disappointed as I expected more from Icebreaker. My old ones have lasted many years and have been great, it doesn't seem to be of such good quality.
Pros
One of the best things I've ever had. Light, warm, odorless. Dries very quickly Absolutely perfect
Cons
This shirt is relatively expensive compared to other long sleeve t-shirts on the market.
