This is my 4th purchase: in both long and short sleeves, in white and blue, it's a great product. Breathable, comfortable to wear, good fit. The ML version is TB as a winter first layer.

First layer already tested on the trail (still a bit warm for autumn), and on the long distance route (great feeling, it's soft and pleasant to wear!) A little tight in the forearms (impossible for me to roll up the sleeves) but that's the only complaint. Great product
