Quiksilver Cypher PS+ Heat Vest

A must have item for cold temperate conditions. The Cypher vest has two kidney heat panels that can last 2.5hrs per session after a full recharge. The settings can be changed to high, low or off for more control over the temperature inside the wetsuit. This heat vest makes a 4/3 or even 3/2 wetsuit achievable in the depths of winter.

Here's what Quiksilver say:

Quiksilver introduces the first ever battery powered heat vest that can be worn and operated under any wetsuit.
Utilising FAR infra-red heating technology, the Cypher PS+ Heat Vest system delivers hours of heat to vital organs maintaining your core temperature and extending your session.

FAR infra red heat technology ids a safe and therapeutic form of heat that is free from hot wires or electromagnetic fields.

This technology has been incorporated into flat flexible carbon pads to distribute heat when the system is powered on.

The pads are combined with a lightweight polypro vest which can be worn under any wetsuit and serves as an additional thermal layer.
