Merino active shirt

Have many merino wool shirts from various brands. These are by far the best for sports activities - trail running, hiking, biking, etc. Two requests - more colors please and please try to keep them in stock!

Active Merino T-Shirt

This is my third purchase and they are perfect for more active pursuits in warmer weather. I like how they fit, how light they are, and how they don't smell from one sweaty adventure after another. I would definitely appreciate more color choices!
