Multi-body helmet construction and strap attachment method

A helmet comprising:

• an upper-body comprising a first outer shell coupled to a first energy-absorbing shell formed of expanded polypropylene (EPP), expanded polystyrene (EPS), expanded polyurethane (EPU), or expanded polyolefin (EPO);
• a lower-body comprising a second outer shell separate from the first outer shell and coupled to a second energy-absorbing shell separate from the first energy-absorbing shell formed of EPP, EPS, EPU, or EPO nested within and substantially coextensive with the upper-body;
• a strap anchor disposed between the upper-body and the lower-body, the strap anchor comprising a housing with an opening formed through the housing and sized to receive a fastening device through the opening, wherein the strap anchor is sandwiched between the upper-body and the lower-body with the strap anchor being adjacent to, and oriented towards, the lower-body;
• and
• a strap coupled to the fastening device and coupled to the strap anchor, wherein the strap extends between the upper-body and the lower-body for coupling the upper and lower body together and coupling the helmet to a head of a user.
