UPDATE: I've spoken with the folks at Scott USA about linking people to local bike shops carrying their MIPS-equipped helmets, and they directed me to this shop locator. I've tried it a couple times and it works really well. They say more shops are stocking the Taal and Lin as interest increases, but it's still not a top seller and you may have to special order one.
I've already gotten a number of queries about which next-generation helmets actually mitigate the risk of concussion. There are only a few on the market at this point. Scott USA has just launched two, the Taal and the Lin, which both have the MIPS system. The Taal (pictured at left) looks to be the one with the best price point, around $75, and I found some here at Suburbanskiandbike.com. REI carries POC's Trabec Race helmet, which also has the MIPS system. It's a more rugged lid meant for mountain biking, and it carries a rugged price ($220). For snow sports, I love Burton's RED helmet with MIPS. I skied with it this past season, as did my wife and kids. REI has them on sale right now for $119. I've seen even better deals online at skis.com and altrec, but with REI you get the easy return policy if you need it. Amazon has Scott USA's Chase snow helmet, with MIPS, for around $106.
FOR HOCKEY PLAYERS: In the helmet industry, hockey helmets are notoriously the absolute worst sports helmets. Seriously. It's like a joke. A couple months ago I ditched our old helmets and bought myself and my son a Messier M11 helmet, which is advanced as hockey head protection gets. They don't have the MIPS system, but operate on sort of a similar principle of giving the head room to move and slide. We've been wearing them for 2 months and frankly I love it. It's the lightest, most comfortable hockey helmet I've ever worn. Check it out at Cascadeicehockey.com.
As I wrote in the article, if riders and skiers want better brain protection we have to vote with our wallets. Nobody's forcing helmet makers to care about concussions, and if these helmets don't sell, their manufacturers will get the message and drop the MIPS system as well as future concussion systems already in the pipeline. Go out and get your brain protected now!
