This is the third of these tops I own and all three are still going well (the oldest is 5 years old). Perfect for winter climbing or bouldering in cold conditions.
Good fit and a nice feel to the top. Unfortunately all thread came out the back and on one sleeve so had to send back. I don't know if it was a line defect or there prone to this. Though I would have to say the top was very thin quoted as a 250 gm2 I have other base layers at 185gm2 that felt the same thickness. Made me wonder if the thread was just too thin and fragile.
