Features
The Extreme 400 Jumpsuits the warmest jumpsuit Santi offers. It is designed for diving in water temperature less than 38 degrees Fahrenheit. It is also ideal for long deep diving, with decompression. Highly experienced divers and instructors helped us develop this Jumpsuit.
The best materials and technologies available are used to produce this Jumpsuit. Thinsulate™ insulation is recommended by 3M as optimal for diving jumpsuits, because it is compressed and does not take as much space under the Dry Suit as would other materials.
The Extreme 400 Jumpsuit also has a net layer, which make the jumpsuit even more durable and practically indestructible. The lining is made of soft micropolar 190 gr. The outside layer is made of Pertex, additionally reinforced with polyester fabric in the areas exposed to damage. This is the model that we've gained initial experience on and used it for development of our other models. Use of elastic gussets in arms and waist, wide ankle bands and water-resistant cuffs with loops that supply air to the dry gloves are some of the examples.
