This product is the result of an intelligent combination of two existing solutions: a bag for sliding sports and protection for the back. The expense of extra protection deters people and many sliding sports practitioners do not get round to acquiring back protection. But now safety is within everyone’s reach – for the price of a rucksack. • The rigid shell helps to protect the contents. • An elastic neoprene belt (with no buckle) holds the bag to the body, preventing it from moving during sports. Since the cost of a product is increasingly linked to the costs of its logistics, distribution and storage, the combination of two products in one results in savings for the user.
