I bought this about a year ago and immediately realized that it was a little bit snug for me to wear as a midlayer (which is what I had in mind). I bought a size L in the next drop and have loved it ever since. This size M is slightly too small for a 6′ 1″ 175lb man, unless you want it as a baselayer. Price includes shipping and it will come in the original Senchi bag.
