Being cold underwater is one of the most important reasons for having to get out of the water. It is not without reason that more and more (seasoned) divers use a Thermalution heating vest to dive longer and more often, even in colder water.
It has been quite a few years since Thermalution introduced the Power heated vests. Actually nothing has changed in the basic concept of these FAR infrared heating vests. Recently the Power Heated Gloves have been added to the Thermalution family.

One of the most popular models among divers is the YELLOW GRADE. Guaranteed waterproof up to 100 meters and can therefore be used under a dry suit and a wet suit. No worries about possible water damage in the system. The Yellow Grade works with a wireless, waterproof, rechargeable, remote control with which the vest can be switched underwater and on land. The heat vest has 3 heat settings, of which level 1 (green) is often sufficient for under a dry suit. When using a neoprene wetsuit, level 2 or 3 with more heat can sometimes provide more comfort.

Thermalution uses the unique ThermalTec heating system that generates FAR infrared heat. This is the same heat as the (red) heat lamp in the sauna and the same heat frequency that we experience as solar heat when the sun is shining. This comfortable heat penetrates deep into the skin, so that the body's heat circulation system can absorb this heat and distribute it throughout the body. It is a compact and efficient system that uses little energy, but can give off a lot of heat. It can generate heat up to 4 hours with a small battery pack. The positioning of the heating element is on the back. This is where the least fat is on the body and the heat can penetrate the body most easily.

The Yellow Grade (plus) is now succeeded by the new Yellow Grade 2.0. The same principles, but just a bit more modern. For example, the pockets where the batteries were placed are no longer permanently mounted, but now they can be placed anywhere on the side of the vest with the help of a Velcro pocket. The side panel of the vest has therefore changed material to be able to touch the pocket. A ride has been added to make it easier to put on and take off.

The batteries have been electronically modernized, so that it can control 2 products at the same time. So that the vest can be used together with the Power Heated Gloves. The size of the battery has also become somewhat flatter. This makes it a lot more comfortable. The battery has an inscription V2.

The set of the Yellow Grade 2.0 consists of the vest, a rechargeable remote control, 2 batteries (SPE-002-I), a charger (110/220 volts) to charge the batteries and the remote control.
