The Billingham SP50 Black Leather Shoulder Pad. is ideal for using with Billingham bags where extra padding and comfort is required. The SP50 strap fits a 50mm (2inch) strap and is easily attached to the strap by undoing the poppers. M Billingham & Co was founded in 1973 and still runs as a family business today. The bags are a UK success story as they have been conceived. designed and made here in the United Kingdom as a spin off from fishing bags. apparently the photographers of New York bought the fishing bags to carry their camera equipment in. and the rest is. as they say. history. The bags have solid brass fittings. top grain leather and waterproof canvas which is specifically chosen for its natural properties and remarkably is incredibly resistant to the weather the UK has to offer. Billingham have branched out into synthetic fibres. which are still tough and hard wearing. but slightly lighter than the canves versions. The FibreNyte is a super durable fabric which has been bonded to a polyester lining using the Billingham StormBlock butyl rubber. This measn that the bag weighs approximately 10% less than the traditional canvas bags. It is remarkably soft. which helps eliminate any abrasion and colourfast as the dyes are bonded to the material. The bags are a particularly good buy as they retain their resale value. due to their longevity.
