“I wore the Sprint LS shirt running in 50F weather. Compare to other Merino shirts I wore before, the Sprint LS is a lot more breathable. It also dries faster and wicks sweat quicker. I highly recommend it. I don’t find it itchy at all. It’s soft and comfortable.
The only thing I don’t like is that it is a bit too long on me. I am 5’4”, and ordered a small. It fits a bit loose at my waist but perfect at my shoulders.”
