TOG is a recognised measure of a textile’s thermal ability. Simply put, the higher the TOG rating, the better a product is able to keep you warm. The ribbed construction of these long johns shapes to the bodies’ natural contours and that along with the soft brushed insides maximises the warmth! The Cotton blend and the elasticated waist provide natural softness and comfort.
