First impression
Except for the name, the jacket doesn't have too much in common with the Nuclei FL already reviewed on PowderGuide.com. Of course, both are synthetic fiber insulation jackets with hoods. However, while the FL (Fast & Light) is designed to be lightweight, the AR (Allround) is more robust and significantly warmer, but also heavier. The jacket makes a warm and durable impression, but is still quite light and compressible thanks to the well-known high-quality Coreloft insulation. The jacket has hand warmer pockets on the outside and a large mesh pocket on the inside. The cuffs are elasticated and the waistband and hood are of course adjustable.
I've been wearing the jacket since mid-January, it fits well and is comfortable to wear, both as an outer layer and under a hard shell. I am 183cm, weigh about 75kg and wear size L.
