Purchased this product knowing that it lacked back protection, but hoping that it would have sufficient protection around the collarbone and rib cage. The product arrived quickly (usual BTO efficiency!) but I was disappointed for the following reasons: - the product quality is less than expected in terms of materials used and workmanship (the photo looks much better than the product!) - the protection around the rib cage is poor - the product fit is larger than the fitting charts would indicate On the plus side it is well ventilated and stays cool while riding in hot weather. Overall, it does not fullfill the requirements for which it was purchased.
