Constructed with extremely dependable Thermoplastic Laminated Carbon (TLC) shell technology, combining the elasticity of injection-molded thermoplastic with the rigidity and strength of carbon fiber. It enables Sweet to effectively tune the shell for different properties in different areas: the shell is softer in the crown area, which due to the rigid spherical geometry is better for impacts and stiffer along the sides where the larger radius benefits from the rigid carbon fiber. Carbon fiber represents more than half of the total area of the top shell.
