I'm wondering about everyone's experience with the durability of the currently available light merino wool shirts from different manufacturers. I ordered a couple of Smartwool "rambidextrous" (sp) shirts. They're comparable in thickness to some of my polyester shirts. I noticed that they fuzzed out a bit on the first wash, not to say that that's a problem, but it did prompt me to wonder about what to expect for the long-term durabiliity of them, and if there are some shirts that are more durable than others? Do some fuzz out and pill more than others? The polyester wicking shirts are very cheap, but these wool ones are quite an investment.
