This is my second pair of the Targhees. Granted, I wear them a lot but both pairs have had the seams come apart within a year. They are comfy, which is why I tried a second pair. Won't buy them again.
I am converting a lot of my baselayers to wool and wanted to try Patagonia merino 3 to see how it compares to other wools. Don't like the feel of the fabric...and..it really isn't warm. It might be a good spring or fall layer but will not be part of my winter layering. Icebreaker or Ibex are much warmer and have a nicer feel next to the skin.
