As to the material we looked for the perfect kind of shell quality. It is made of EVA material :
Ethylene vinyl acetate (EVA) is the copolymer of ethylene and vinyl acetate. Its an extremely elastic material that can be sintered to form a porous material similar to rubber, yet with excellent toughness. It is three times as flexible as low-density polyethylene (LDPE), showing tensile elongation of 750% with a peak melting temperature of 250°F (96°C).
This material has good barrier properties, low-temperature toughness, stress-crack resistance, hot-melt adhesive waterproof properties, and resistance to ultraviolet radiation. EVA has little or no odor and is competitive with rubber and vinyl products in many electrical applications.

EVA is one of the materials popularly known as expanded rubber or foam rubber. EVA foam is used as padding in equipment for various sports such as ski boots, hockey, boxing, mixed martial arts, wakeboard boots, waterski boots, fishing rods and fishing reel handles. It is typically used as a shock absorber in sports shoes, for example. It is used for the manufacture of floats for commercial fishing gear such as purse seine (seine fishing) and gillnets. In addition, because of its buoyancy, EVA has made its way into non-traditional products such as floating eyewear. It is also used in the photovoltaics industry as an encapsulation material for silicon cells in the manufacture of photovoltaic modules. EVA slippers and sandals are nowadays very popular because of its properties like light weight, easy to mold, odorless, glossy finish, and cheaper compared to natural rubber. In fishing rods, it is used to construct handles on the rod-.... end. EVA can be used as a substitute for cork in many applications.
