super light! could easily and happily wear it all day. but the back pad, d30, vpd or otherwise, is simply too thin and unstructured to do a decent job for protecting you in a crash. no scapula protection. shoulders and chest are great, so that's the issue here.... great shoulder and chest armor, but the spine protection is a 3/8 foam pad? sure it's better than just foam, but it isn't rigid plastic, and this is your spine we're talking about here, I want some hard plastic on top of this foam please. The separate POC spine protector is sure nice (not sure that you can get it at hullnroll) and it should be part of this product.
