The new HTR hydration system from The North Face relies on the power of both insulation and thermal technology to ensure the tube from your hydration bladder stays warm enough that the liquid inside never freezes, no matter how far the mercury plummets – leaving you free to concentrate on your next adventure rather than worry about how long you can go without another gulp of water.

Simple and easy to use, the HTR uses four AA batteries to power an active heating system encased in the insulated drinking tube cover to maintain vital fluids in the liquid, and therefore drinkable state. A sensor monitors the temperature of the hose and signals the system to heat when it approaches freezing – ensuring that precious liquids never freeze.

To protect the vulnerable bite valve, these packs have a zippered, insulated garage on the shoulder strap to keep out the element. Finally, an easy to read LED on the drinking tube cover provides ongoing information about the system’s status: heating on or off, as well as a low battery indicator.

The HTR is available this winter in a 12 litre daypack size – the Snowday – which will also carry either skis or a snowboard, and a smaller 4 litre sleeve for fast moving activities (Flask) where you only want to carry the bare minimum. Thoroughly researched and exhaustively tested, the HTR system will operate for at least 20 hours at minus 10 degrees C.

Keith Byrne, Sales & Marketing Manager for The North Face said, “We are really excited about this new system which provides the outdoor athlete with a powerful new tool for staying hydrated whilst taking on the harsh realities of winter”.
