The Men's Reactor Jacket by Marmot. A classic 100-weight fleece that looks as good as it feels; the Reactor Jacket sports a wind flap behind the front zipper to block chilly drafts. Angel-Wing Movement means absolute freedom of movement, whether worn as a jacket or underneath a shell as a warm mid layer.
It's super light weight, great over a t shirt or under a shell. It's zip-in compatible and I use it in a vagabond gtx jacket. Very nicely constructed and detailed, but since I don't smoke any more the stash pocket on the arm seems a little useless.
This is definitely meant to be a "lightweight" jacket, but I wear it quite a bit when it's not too cold. I love it for wearing around the house, and I have it sized tighter so I can wear it under other layers. It's so soft and comfy, I wear it whenever I can! Quality materials and manufacturing.
I'm very happy with this jacket. Being a 100 micro fleece it's obviously not going to be super warm, but it's comfortable, light, has a nice fit, and can be used as a midlayer if it's really cold. I like the zipper a lot, it seems sturdy. For reference, I'm 6" 165# and the M fits perfectly.
I bought this jacket for my husband for his 32nd birthday and he loved it minus the color. He is 6 ft. and 175 lbs. and the large was a perfect fit. The coat was extremely soft and comfortable, I even tried it on. Very light and could fit in his golf bag for the fall when it's chilly outside. As for the color (light grey) it had almost a pale blue color to it, it was more of a girlie color I think! He ended up exchanging the jacket for a different jacket all together - Patagonia. Overall, the coat was what I had expected however if had it been a better color he would have kept it and you can't beat the price.
