I have probably way too much Merino stuff from Icebreaker: t-shirts, collared shirts, underwear, shorts, jackets. I used to sell the stuff and got hooked at that point. I like the look and the feel of the wool, especially in the t-shirts as the colours are very vibrant and I find they wear very well (I also sweat a great deal, but I have no issues with itchiness, although it definitely is a different feeling than cotton next to skin). I find the fabric is, umm, not very flattering if one has put on a few pounds though, and as such I seem to have an almost even collection of size Medium and size Large t-shirts. But that must be be at least partly because my weight fluctuates a little and I'm also generally between sizes. Anyway, I love how quick the stuff dries and their odourphobicness (especially the t-shirts). They are amazing for travelling. Their underwear is great too, but I will say that I have torn two pairs of those before, which--considering their price--was disappointing, and as such I've not bought them again.
