  • Description

    The Thermalution Yellow Grade Plus heated vest is a excellent way of maintaining your body temperature on those long or particularly cold dives. The heating elements allow warmth in three different output levels to be injected back into your core, making the rest of your body and extremities feel toasty and warm.

    The vest uses two rechargeable batteries that are mounted vertically beneath the arms to fuel the heating elements. The temperature output is controlled via a remote units that can be fitted to your wrist or secured to your kit and features a simple slide switch button to cycle through the power levels. A low profile receiver mounted in the low back of the vest acknowledges the setting changes by gently vibrating, letting you know your commands have been received and actioned.
