If you're not much of a fan of the layering system and just want one warm jacket to cruise the pistes in, then look no further than Rossignol's Rapide. The Rapide features a hefty chunk of down like synthetic insulation and a flattering, tailored cut which looks great both on and off the mountain. If you're at the top end of your usual size, then go for a bigger size to ensure that you can still move freely. With 20K/20K waterproofing and breathability we found this jacket performed perfectly during long days on the pistes, especially in colder weather. Critically taped seams protect you from slow water ingress in the most vulnerable areas; fully taped seams are great, but would no doubt increase the price of the jacket and are not strictly necessary for piste skiing.
Features wise this jacket keeps it slim, trim and aesthetically pleasing with a couple of fleece backed handwarmer pockets and a lift pass pocket on the lower arm as well as an internal mesh dump pocket for hats and gloves. There's a decent powder skirt to keep the snow out and an adjustable hem and hood. The hood is functional and comfortable if not highly technical.
At £227 this jacket represents superb value for money thanks to excellent build quality and choice features.
