4th Element SUB-30 Technical Garmet Wash
We have been asked so many times what the best product is for washing fourth element thermals. Over the 4th Element tried many different washing detergents: some had built in softeners, others had optical whiteners and others were just too damaging to the environment. Finally, they decided to work on our own specially formulated detergent for washing technical sportswear at low temperatures.

Santi Heated Vest
The Santi Heated Vest is perfect for divers who need more insulation than can be provided by 'passive' undersuits. The Santi Heating Vest actually actively helps to keep you warm, it is not designed to warm you up but to limit the rate at which you become cold. As such the heating vest does not feel 'hot' but it's effects can be felt.

Limited to a maximum working temperature of 40oC chances of burns from the vest are highly unlikely. At 60 watts of power the vest requires a battery pack located outside of the suit, a 10 amp hour battery will last for around 1.5-2 hours, while a 20a/hr battery will last 3-4 hours.

The Santi Heated Vest is made from 200gr thinsulate to provide you with insulation even if the vest inst plugged in. The vest is firmly fitted with elastic in the sides and an elasticated velcro crotch straps to keep the vest exactly in position. The vest is already fitted with a terminated cable but batteries and a through-suit connector must be purchased separately.

DirDirect is a world-leading online dive shop run by Underwater Explorers based in Portland, Dorset, UK. Underwater Explorers is a dive centre with a striking difference. It was born out of the concept of "Hogarthian" diving, safe and streamlined equipment configuration, using the most robust products available for recreational and technical diving -- but at the same time, keeping it simple. It is based on the concept of "less is more" in diving and acts as an equipment outlet, training facility and source of sound advice.

Thank you for the excellent service and reasonable prices! I will highly recommend your store to my friends.
