The following information is from Sparco's website,
The Evo II has the quality and value you have come to expect in the Evo seat line including a unique shell shape and fiberglass construction that increase rigidity without adding weight. The Evo II introduces re-engineered seat proportions, which provide greater ergonomics. The result is a seat that is both taller and slightly wider than the EVO for taller drivers. The seat belt slots are also repositioned to sit more level with the driver’s shoulders. The Evo II can accommodate a Hans device. The Evo II is FIA approved.
