These requirements meet the terms of Icebreaker merino wool because of the very good.
Icebreaker is interesting for everyone, the outside is much movement in or travels a lot (possibly backpacking, etc.) The Merino fabric ingests only very bad odors. That means you have to wash the clothes rarely.
My Everyday Shirt I did not even wash now since about 4 weeks and in the entire period. Well, I have not worn every day around the clock. But as good as every other day and then from morning to night. Although I was sweating a little each time wearing, has not yet developed a nasty smell (especially under the armpits) so far. The fabric also dries very quickly - even while wearing.
The material of the Everyday Tops is very thin (I think 200g / m²). However, compared to cotton or synthetic substances having the same thickness, the merino keeps much better warm. Now in winter the Everyday is the only layer under a parka certainly not enough, but there are still a number of other clothes Icebreaker :)
On the subject of wool and scratching: My skin is quite sensitive and there have been incidents often that I have tried something in the store and it could not buy, because the wool was too scratchy. The Icebreaker stuff that's not so. In the tight-fitting things like the Everyday or Anatomica the substance in the first Carry me a little bit but has gepikst not thereafter. I think everyone should try for yourself because everyone is different and feels different.
