loganschnurI can name 3 without thinking.
ON3P, Liberty, and RMU
Don't think too hard. Most people don't make their own skis, and even fewer do so in North America.
Liberty is made in China.
RMU is made in Denver (Never Summer) and Quebec (Utopie).
Never Summer is also building Icelantic, Fatypus, and High Society.
Utopie is also building Jskis, HG, and Stanston.
Goes for Europe, too, where you see Faction, Apo, Amplid, Majesty, White Dot, and so on all be made by large factories over there.
There is a huge difference in my mind between companies building their own product and those paying to have someone else build their product (in both North America and Europe). That isn't to say that these companies outsourcing production build bad skis - just that the job they do and the one done by those who build their own product is vastly different. I consider ON3P a manufacturing company. We compete with a bunch of design and marketing companies.
There are TONS of small builders building in North America right now (say anywhere from 50-750 skis per year). But if you are looking for real factories running production volumes (say, at a minimum, 50 pairs/week) in the North America building their own product? Only ones I can think of are ON3P, Moment, Praxis, Ramp, DPS (Pure skis only) and Mervin (and most of Mervin's production is snowboards). Pretty small group when you get down to it.
Also, should be stated that there are good skis being build in North America, China, and Europe, just as there are bad skis being build in North America, China, and Europe. For me, I have a lot of respect for companies who build their own products because I know just how much work goes into producing skis. That's just me though...
