Cressi-Sub is an Italian manufacturer of scuba gear and one of the oldest underwater diving companies presently existing. Officially, the company was founded in 1946 by brothers Egidio and Nanni Cressi, although they had already begun small-scale manual production in 1943.
The history of underwater diving itself is connected with the history of Cressi-Sub, and many Cressi products have marked the evolution of this sport over the past sixty years, with a series of inventions and insights that were then followed by all the manufacturers.
They continued to make sport diving oxygen rebreathers until after 1960. Now Cressi-Sub is a worldwide manufacturer and distributor of professional diving and swimming equipment.
