Longs Padded is a great pair of 3/4 length long-johns in merino wool, made in a mid-weight that makes it perfect for all kinds of activities in cold weather. In addition, is has the slightly unusual detail of having a pocket in the back and knees for padding.
The idea was born while sailing from France to Norway. After sitting for hours on end without any cushioning, the crew cut up styrofoam boxes to make padding they could put in their pants. It worked as long as they were sitting still, but as soon as they stood up it was useless. But what if the padding was flexible and built into their clothes?
