It sure will keep you warm on a cold dayBut polyester is not really sweat absorbing and doesnt really let your skin breathe, like CottonSo it will keep you warm but you will also sweat like a pig.but its easier to take care of than a Cotton Jumper, which might shrink or crease while washingSo i guess its a good bargain for $40Just keep it.or check Ebay for a better bargain on sweaters!
