Very stylish
Color: Khaki, Size: Medium
My husband doesn’t like wearing pullover sweaters because he gets hot after being inside for awhile. This sweater jacket was perfect. It’s stylish and well made. Very comfortable and great price. When I gave him the pkg and reminded me he didn’t like sweaters inside. When he opened it and was pleasantly surprised. Finally he could wear a sweater that was easy to put on and take off. He loved everything about it. I bought more colors and he wears every one of them. Great sweater!

Comfortable, warm enough. Feels a bit like a shawl but looks like a good sweater.
I like the color and the fit is good, roomy, feels a bit like a shawl but holds shape and hides a few extra pounds. The zipper is thin but whether you'll find it good enough to last I wouldn't know yet. I'm keeping this.
