This is simply a brigandine vest (see Brigandine Doublet) worn over a heavy gambeson (see Gambeson and Helm), and a full helmet. This is medium weight, reasonably light armor which provides good coverage and pretty good overall protection. The first row represents the protective quality of the helmet or the brigandine and the gambeson, the second row represents the protective quality of the gambeson alone. See Armor Table Key, Layered armors for more about how this works.
