Went down a mid-weight/mid-layer hoodie rabbit hole and kept coming across this. I loved the idea of a scuba hood and thumb holes and it looked good so I pulled the trigger. WOW! This thing is awesome! It's extremely comfortable, not too heavy, but surprisingly warm. I am 5'9" and around 180, and I was afraid a medium might be too small, but it first me perfectly. It's slightly bigger than a true medium, which I love. On me, it's roomy enough to wear over a t shirt without it being too snug. One thing that I also really appreciate that I haven't seen anyone say is that the circumference of the wrist opening is not overly large. It ever so slightly hugs the wrist so that the sleeve won't keep slipping over your hand. Love it. A very well thought out design and cut that I never want to take off. Get it!!
