1. A protective sports helmet capable of being worn by a player while engaged in a sporting activity, the protective sports helmet comprising:
an outer shell; and
an energy attenuation assembly having a plurality of energy attenuation members removably coupled within the outer shell, wherein at least one energy attenuation member of the plurality of energy attenuation members is manufactured from an additive manufacturing process and includes:
a first region: (i) having a height and a width of at least one lattice cell that is a strut-based lattice cell type, and (ii) requires a first force to compress the first region, and
a second region: (i) that is integrally formed with the first region, (ii) having a height and a width of at least one lattice cell that is a surface-based lattice cell type, and (iii) requires a second force to compress the second region, and wherein said second force is greater than the first force.
