I have some First Lite too in a head balaclava and I like it too but I have more of the Icebreaker. I saw Icebreaker Merino wool shirts get some awards in Backpacker magazine years back, got some back then and love it for backpacking. I like the different weights too. I use lighter weight in summer and it works well in hot and cold weather. I have some heavier weight stuff for winter too. I think the only drawback has been price but it is a good product and it wears well.I was looking at the 260 top and 200 bottoms on sale for 35% off but still pricey. I just hate ordering things offline without seeing them first or hearing about it. Have you had any experience with first lite? Wondered how they compare but from what i can tell the FL doesnt come in different weights like the IB.
