UPDATE: Venture Heat was backordered most of 2021 due to shipping issues. Hopefully back in stock last quarter of 2021. Please check back.
These vests have heating both in the front as well as in the back of the vest. The 2 models we recommend are the D616 40w and the Thinsulate D617 40w. The D617 is made with 200g 3M Thinsulate material for additional insulation! Both are rated to 100m/330ft. Each vest comes with a wireless remote, batteries, and chargers. We suggest ordering 1 size larger than your normal t-shirt size. Each vest comes with an additional 3 inch zippered insert that can be zipped into the vest for a truly custom fit! Both models come with two heat panels that provide 40 watts of high output warmth to the user’s torso. Each powered from the two 5200mah lithium batteries that can be activated by pressing the button on the wireless wrist remote. Incorporated into the undersuits is a haptic status receiver that sends feedback to the user via pulses regarding the 3 heat levels, which works well even with obscured vision while underwater.
