I was somewhat uncertain about this since it seemed a bit thin but decided to give it a try since the weather is now dropping below freezing. I love this and wear it almost daily. I generally wear it like a light jacket rather than a baselayer and it is just enough to take the chill off. I also tried it as a baselayer while hiking. It was fantastic. I shed layers while going up to just this and was fine at about 40 degrees. I added a vest when coming back down and not working as hard.
Even though I wear it like a jacket, its not going to block any wind so use it under something else if its windy.
Overall, I really like this and would 100% buy it again.
