The Venture Heat DRY V3 Waterproof Diving Vest is a purpose-built heated undervest for drysuit divers tackling cold water. Two large heating zones cover the chest and back to maintain core temperature throughout extended dives, while a wrist remote with haptic feedback lets you adjust settings through thick gloves in low visibility. Rated to 100 m (300 ft), it runs up to 360 minutes on two included 12V waterproof batteries.
Product Overview
The vest sits under the drysuit as a dedicated thermal layer, targeting core heat loss where it matters most. A large chest zone and large back zone deliver consistent warmth without restricting drysuit mobility or gas inflation. The outer shell is 100% nylon with a polyester lining and 3M Thinsulate insulation, keeping the vest lightweight and low-profile enough to fit comfortably inside most drysuits without adding meaningful bulk.
Power comes from two included 12V Venture Heat waterproof batteries, providing up to 360 minutes of runtime per charge. An integrated on-body button handles power and heat level control, while the wrist remote uses haptic feedback to confirm adjustments by feel rather than sight. This matters in cold water with thick gloves, where fumbling for controls costs warmth and attention on every descent.
For divers exploring our wide array of dry suits and cold-water diving gear, the DRY V3 addresses the thermal gap a drysuit alone cannot close. Consistent core warmth reduces fatigue, steadies gas consumption, and extends comfortable bottom time across cold temperate and technical diving environments.
Two-Zone Core Heating Built for Drysuit Use
The DRY V3 targets the two body regions responsible for most heat loss underwater: the chest and the back. Each is covered by a large independent heating zone, providing broad, even warmth across the torso rather than the narrow strips found in lesser heated garments. Combined with 3M Thinsulate insulation throughout, the vest maintains thermal protection even between heating cycles when the elements are drawing heat away fastest. The low-profile construction keeps the vest from adding bulk that would interfere with drysuit fit or buoyancy trim.
Haptic Wrist Remote and 360-Minute Battery Life
Two 12V Venture Heat waterproof rechargeable batteries are included in the box, delivering up to 360 minutes of continuous heating per charge. In practice, divers can run the vest at moderate settings through a full day of diving without recharging mid-session. Heat adjustment is handled through a wrist-mounted remote controller that delivers haptic pulses to confirm each command, eliminating the need to look at a display or remove gloves in cold water. The integrated on-body button also provides direct control for simple on/off and level changes without reaching for the wrist remote.

FAQ
The DRY V3 is designed as a universal heated undervest for drysuit use and is intended to fit inside standard drysuit undersuit systems. Compatibility will depend on the cut of your specific drysuit and how much internal volume it has. If you are unsure whether the vest will fit your setup, contact our team at sales@bluewaterphotostore.com and we can help you assess the fit.
Two 12V Venture Heat waterproof rechargeable batteries are included, providing a combined runtime of up to 360 minutes. Actual runtime will vary by heat setting — lower settings extend battery life significantly. Recharge times are not specified by Venture Heat; for exact charge time data, contact us at sales@bluewaterphotostore.com.
The vest includes both an integrated on-body button and a wrist remote controller. The wrist remote uses haptic feedback to confirm each command, so you can adjust heat levels by feel through thick diving gloves without looking at a display. The on-body button also works for basic control without reaching for the remote.
No. The DRY V3 is designed specifically for drysuit use. It is not intended to be used inside a wetsuit, where water ingress would compromise both the vest and the battery connections. For heated wetsuit options, reach out to our team at sales@bluewaterphotostore.com and we can point you toward suitable alternatives.
The DRY V3 is rated waterproof to 100 m (300 ft). This is a genuine dive-rated waterproof construction, not surface splash resistance. The 12V batteries included are also specifically described as waterproof, making the entire system suited to submersion at recreational and technical diving depths.
Venture Heat recommends using your standard USA unisex T-shirt size as a starting point. If you are between sizes, sizing down is an option because each vest includes a stretchy zip-in expansion panel for an adjustable fit. When sizing for drysuit use specifically, consider that the vest must fit comfortably under your undersuit. If in doubt, contact us at sales@bluewaterphotostore.com for guidance.
