The Aqua F12 Thermal Jacket is a hi-performance jacket for extreme weather conditions. The jacket has an innovative silver lining that has been cross-weaved to help increase heat retention and prevent the jacket from being bulky like other winter coats. 

The Aqua F12 Thermal Jacket offers four main properties: 

1. It's Waterproof with a 10,000mm Hydrostatic head.
2. It's Windproof, so it will cut out that chilling wind that can make you feel really cold.
3. It is Breathable as it has a 5000 MVP, a high-quality breathable performance fabric.
4. It has Extreme Warmth.

All the seams are sealed to keep the water out, and a high-quality hollow-fill lining keeps the jacket light and extremely warm. The back of the jacket extends to keep your lower back warm and to help prevent it from riding up when sitting in it. Also, there are velcro cuffs to the sleeves and an adjustable tailored hood that offers improved protection from elements without impacting your vision.
