Extreme Diving Heated Undergarment Socks

Extreme Diving Heated Undergarment Socks: Don't Let Cold Feet End Your Dive!

Are cold feet the first thing that sends you heading for the surface? The Extreme Diving Heated Undergarment Socks are the active solution to keep your toes warm and comfortable, allowing you to stay focused on your dive, not on the temperature. This is a key component for any serious cold-water drysuit diver.

How They Keep You Warm:

These socks feature heating elements that run along the bottom of the foot, delivering consistent, active warmth where you need it most. They are designed to heat up to approximately 105°F (40.5°C), depending on your battery's voltage. The socks themselves are made from a comfortable, dual-layer fabric, with a durable Polartec® Power Stretch® Pro exterior and a soft fleece interior that provides excellent insulation even when the heating element is off.

System Requirements & Integration:

These heated socks are part of a modular system and require a power source to function.

• Why it Matters: To operate them, you will need a compatible drysuit thermovalve and an 11-12V external battery pack. The included 60-inch (152 cm) wiring harness is long enough to easily run from the sock's connector up through your undergarments to your chest-mounted thermovalve. If you plan to use these with other heated gear like a vest or gloves, you will need a 2-way or 3-way splitter (sold separately).

Power Draw & Estimated Runtimes:

The socks draw approximately 28 watts of power. Your expected runtime will vary based on your battery's capacity (Ah) and what other heated gear you are powering at the same time:

• Socks Only:
  • 10Ah battery: ~4 hours
  • 20Ah battery: ~8.5 hours
• With 55W Vest + 36W Gloves:
  • 10Ah battery: ~1 hour
  • 20Ah battery: ~2 hours
• With 110W Full Suit + 36W Gloves:
  • 10Ah battery: ~0.6 hours (approx. 36 minutes)
  • 20Ah battery: ~1.3 hours (approx. 78 minutes)

Valve Compatibility Note:

Please verify your connectors! This system's harness uses a female push-lock connector. It is directly compatible with SANTI and Ammonite valves. Other common valves (like those from SiTech or Light Monkey) may require being retrofitted with a compatible male push-lock connector. If you are unsure about your setup, give our team a call!

The stretchy material accommodates a range of foot sizes. Available in:

• Large: Fits US shoe sizes 8-10
• XL: Fits US shoe sizes 11-13
