Enclosure for a bowling ball

A bowling ball kit comprising:

• (a) a box having an open configuration and a closed configuration, wherein the box in the closed configuration defines an interior cubic volume of less than 730 in3;
• (b) a bowling ball having a diameter between 8.500 inches (21.59 cm) to 8.595 inches (21.83 cm);
• and
• (c) an enclosure enclosing the bowling ball, the enclosure having a flexible inner vapor layer, a flexible outer layer and a flexible insulation layer intermediate the flexible inner vapor barrier layer and the flexible outer layer,
• wherein the enclosure is configured to enclose the bowling ball and be enclosed within the box in the closed configuration of the box.

A method of utilizing a bowling ball enclosure to encase and reduce temperature fluctuations and plasticizer evaporation of a bowling ball, the method comprising:

• providing the bowling ball enclosure, the bowling ball enclosure comprising:
• a flexible inner vapor barrier layer and a flexible outer layer that are made of a polymer material, the flexible inner vapor barrier layer forming an interior region that receives the bowling ball;
• a bottom portion and a top portion, the bottom portion having a concave surface for receiving a portion of the bowling ball and the top portion being positionable from a first position to a second position:
• in the first position, the top portion being open to receive the bowling ball into the interior region;
• and
• in the second position, the top portion being closed to encapsulate the bowling bowl;
• a flexible insulation layer intermediate the flexible inner vapor barrier layer and the flexible outer layer, the flexible insulation layer having an upper configuration to permit the inner vapor barrier layer to contact the flexible outer layer in the second position of the top portion;
• and
• at least one releasable fastener for releasably retaining the top portion in the second position.
