7-30% of body heat is lost thru your head... wear a hat in Winter. Look like Dudley Doright, Nanook of the North, or a warm Buddah wearing this Sears/Dockers' Winter Trooper's Hat and staying healthy. Long ago, I had one of these in rabbit fur, but Sears sells this Dockers' version as 78% acrylic/22% polyester and no animals died. The faux fur is greyish-tan and the sides snap down over your ears.
On 30 NOV 08, this $30 hat was on sale for $18 at Sears. Open a Sears charge account [5 minutes, on the spot] and they'll credit your account $15. That's right, $3 to beat Winter.
