Well, um, we just told you everything you need to know. This has all the features of the B.P in a HappyFit cut producing a slightly wider ride for the more ‘traditional’ body shape. Engineered for maximum impact protection while the TrueFit© Liner moves along with your body and the vest’s outer layer in perfect harmony for a comfortable, friction free ride. The Duraprene© Neoprene material & acute angle cross stitch vest works with the complete stitch through segment panels for the perfect movement and fit.
