Featuring 1000-fill Responsible Down Standard ProDown, it provides pinnacle insulating performance. TNF\'s new proprietary Cloud Down construction enhances warmth further. Offset baffles create space for the down to loft while keeping the lining close to the skin. This minimises cold spots and hugs the body to gives a warm and cosy feel. Finished with a reflective aluminium-coated lining, it captures as much heat as possible. enabling fast layering, full-length side zips and glove compatible zip pulls make them easy to put on and take off. When not in use, the pant packs down small into a special edition FUTUReLIGHT stuff sack.
