So soft and warm
I've been trying to get my husband to invest in one of these for along time, I gave in and bought him one.
He is now toasty and warm (he has hyperthyroidism) and looks lovely too!

Incredibly good!
Very comfortable to wear - feels good on the skin (textile quality!) - also the shape, the cut is good... long on the back. I think it could be a bit longer on the arm (up to the elbow).
