KAMA was founded in 1970 on Taiwan to manufacture the low-end vinyl swim products for export. Through a number of negotiations it finally accepted Elton Corporation in Rochester of New York as the sole agent to market the swim products in the United States.
Strictly speaking, deep-sea diving and shallow-water swimming (swim pools for example) request different standards of product quality. Take a dive mask for an example, its ISO 9002 tempered glass and skirt will have to withstand the impact of high water pressure applied to both while a swim mask subjects to much less water pressure.
