Sparco Eagle 2.0 Driver Suit The Eagle 2.0 is newest evolution of the Eagle suit. The new Eagle 2.0 features an updated, softer HOCOTEX® material which is 30% thinner. The Eagle 2.0 features an all-new design with four new colorways. The Eagle 2.0 carries the newest FIA homologation. SINGLE LAYER CONSTRUCTION, MULTI-LAYER PERFORMANCE The Eagle 2.0 is the result of over 3 years of research and development. Sparco has patented a new technology called HOCOTEX® which revolutionizes the way racing suits are made. This new exclusive Sparco technology creates a single layer fabric which has the protection of what is normally achieved by a multi-layer fabric. The Eagle 2.0 is FIA 8856-2018 homologated. UNPRECEDENTED COMFORT Thanks to HOCOTEX®, the Eagle 2.0 is three times more breathable than a suit produced using traditional technology. The use of this relatively thinner fabric along with large side and back stretch panels and 360 degree arm gussets give the Eagle 2.0 ultimate flexibility and comfort. The Eagle 2.0 uses at new stretch material called Eagle fabric, which is lighter, more breathable, and more abrasion resistant than traditional stretch material. IMPROVED FIRE RESISTANCE Traditional racing suits have layers of fabric sewn together in a quilted pattern. The quilting provides air space between the layers which bloats in a fire, this provides thermal protection to the driver. HOCOTEX® creates a honeycomb structure with internal air cells that ensure the driver even more fire protection. Traditional box quilting creates an average of 300 air chambers in a size 52 suit. The Eagle 2.0 has over 60,000 microcell air chambers which provide a 10 to 12% increase in heat protection performance.
