I'm a merino wool person. I love the material, and thought having a pair of merino shorts would be great for working out since they wouldn't get smelly after one use like synthetic workout shorts. I'm 5ft 10 150lbs. 30 inch waist. The small fit me in the waist but the rest of the fit is weird and doesn't look at all like the model in the photos where the shorts look to be pretty slim fitting. These are very baggy, and they are knit in a way where they are super super elastic. I mean a little stretch is nice but these are over the top in my opinion. The way they hang on my body just looks weird. I'm going to return them.
