I'm not normally a sweater guy as I usually run really warm. Bought this to see how it would do as a hybrid, sweater/jacket. It's perfect. The quality, top notch. Fabric is lush'ish. It has some weight to it, but I didn't really notice it once it was on. Maybe it's the merino (I'm no expert), but temperature regulation is great. I have not had to take it off because I was melting. As you can tell, I'm very happy with the sweater. Well worth the price.
