Pack Monkey is a tool developed by a skydiver, for skydivers. The product is made from a resilient plastic that is crack-resistant, encased in specially chosen fabric to aid in the packing process. The inner plastic corners are also rounded to eliminate risk of the corners wearing through the fabric. The fabric itself was chosen for its durability, and special friction characteristics: There has to be enough friction such that the canopy does not readily slide around when contained by the tool, but also not so much friction that it is difficult to remove the tool from the deployment bag after insertion.
