Although the Pachena Bay has been in continuous production since the early 1990's, this is the first time we have offered it with a full Shearling Lining. Shearling is a type of leather produced from a recently shorn sheep or lamb. The leather is tanned and processed with a clipped layer of wool intact. When used to line footwear, this natural material provides extreme warmth and comfort. Our genuine sheep Shearling is made in the USA and is still a byproduct of the food industry. The combination of this lining and the heavily oiled Chamois leather form Horween makes for the perfect Winter boot.
