Assuming you’ve passed Merino Wool 101, and know it’s not all created equal, there are some great manufacturers, and there are many weights available. In their early years, Kuiu merino wool items were great, as they still are, but they didn’t label them with the weight and fabric information like they do now. If you wasn’t a member of the ILGWU, you probably can’t pick up and older item and tell what the fabric weight is. But for a base layer, that I don’t care whether it is camo or not, I’ve been a buyer of Icebreaker for a long time.
