I have two moncler jackets. A winter down jacket (Branson) and a summer "wind-breaker" style jacket (Pomolos). Both of mine are made primarily of polyamide - a synthetic material that is not very waterproof but which is quite durable (neither of mine have any holes or tears) and which cuts wind. The winter down jacket is the greatest jackets I have ever owned. I can literally withstand pretty much a tundra in the thing. The down is great at regulating body temp so it keeps you super warm in snow storms but you can even wear it when it starts to get warmer. It is not good with rain though and I would never recommend using it as a rain jacket. Contrary to what the previous person wrote, my down coat fits amazing. Perfect around the torso, tight around the waist, sleeves taper down to your wrists so they can squeeze around your gloves, detachable hood wraps your head like a helmet when it's all closed up. They use these things in the alps. They have to fit awesome to retain warmth. My pomolos is SUPER well fitted; short waist line, fitted around torso and sleeves, collar area that maintains shape and shoots out like a starched shirt. I'll take pics when I get home (finally bought a nice camera yesterday). It is super thin and lightweight but when I put it on over say a Paul smith cardigan, I can fly around on my vespa all night without getting chilly. It's good at cutting wind but not at retaining warmth. Mine has these really nice circular vents (about 1cm in diameter) under the arm pits. The zipper and buttons are always really nice quality (metal on the pomolos, thick plastic zippers on the Branson). I wear my pomolos with sleaves up or down. Looks great either way. Moncler jackets usually only have one small emblem (generally on the left side arm) which makes them subtle yet distinguishable to the right eye ;-) like I said before. I LOVE mine. I always get TONS of compliments on them. I remember once I was at a Barneys, I took my branson off to try on some other jacket. When I turn around I see a kid wearing my jacket looking at himself in the mirror and telling his mom he wanted that one. Ha. He was dissapointed when I went over and told him he was actually wearing my jacket which his mom then proceeded to compliment. Cleaning is relatively easy. The down jackets come with a comic strip on the inside that explains how to clean it (a soapy bath; washed by hand). My pomolos I just got recently and haven't exactly read the label but I believe it would be the same thing, just the drying would be much faster since it doesn't contain any feathers. I'll be honest though. Their winter jackets are highly functional & gorgeous. Their summer jackets are mostly aesthetic. If you can justify spending like 700 bucks on a thin jacket to wear in the evenings/night during the summer I say go for it. It will be useful come early fall as well. But dollar for dollar the winter jackets are unmatchable. You can kiss ever being cold again goodbye.
