Another vote for Minus 33. I also have Icebreaker. My icebreaker top has raglan sleeves whereas the Minus 33 has the regular seam. They both work for me. The Minus 33 seems softer and it looks better though I'm not likely to wear it except under another shirt, sweater or jacket. The raglan sleeves would be preferred for archery or technical climbing. I suppose I prefer the -33 since I have several of them and the bottoms.
