Review: L and XL should be right size for older boys - This product should really keep warm. The material is soft with a slight sheen on top and lined with fleece underneath. Unfortunately I had to return as I misinterpreted the sizing. I usually order a S for my 10year old in mens wear. The sizing is for boys and I should have ordered a L or XL for my tall 10year old
Review: Postage doubles the cost of the purchase price. - Does not feel warm, lining gives clammy feel.
