The top is really nice ... texture and feel are good (not as soft as one would expect but that's probably because it's 100% wool) ... it's breathable ... extremely comfortable and fits well (make sure to check sizing chart on icebreaker website just to make sure) ... it's very warm whether on its own or as a base layer ... it's not at all bulky so it fits well under clothings... i found wool to be the warmest base layer and if you are one who gets cold in winter i advise you to pay the extra buck for wool base layers as many thermals out there are hardly worth the money ... i must add that it itches a bit ... but nothing too annoying ... i am happy with my purchase and would never buy anything but wool in the future (my other choice would be Cuddl Duds fleece long under wear ... they are awesome)

I haven't washed it yet but i will sure write an update if anything goes wrong
