Headlamp Helmet Mounting Chapter 1 — Petzl Duo


Post by WildSnow.com blogger | July 9, 2018      

In previous posts, we allude to the fact that most snowsport helmets might not be much more than an expensive hat and, yes, a place to mount a lamp. Well, here you go. I’ve been testing a Petzl Duo headlamp. They sell a nice helmet mount for it, so we did an install on a Salomon hardhat. Works well, with a few reservations.

Front mount fit perfectly, to get the rear as low as I wanted required a bit of trimming.

I’ve been testing the Duo as durable, bright, waterproof headlamp that’ll double as an uphill skiing lamp that’ll double as a helmet light for occasional circumstances such as volunteering for ground search. I’m coming up with a review. Meanwhile, this is not a lightweight unit — it tips the scale at 348 grams. You get a substantial lamp out of the deal, but combined with a dual certified Salmon MTN (pictured) helmet you end up with 708 grams (25 ounces) of demand on your neck muscles. At the least, that means you want all the headlamp components as low as possible on the helmet, for less lever arm. I mounted low for other reasons as well, for example a night mission in the bush with clothesline branches lurking at every step. Configuring in such a way that googles could be stored on the helmet would have been nice, but nothing I tried for that functioned without a lot of mods. I’m not using this for skimo racing, so I’ll be fine with storing my goggles in my rucksack as I’ve done for years.

Shop for Petzl headlamps.

    I’m surprised dynafit hasn’t got you kitted in their helmet with the proprietary headlamp, Lou?

    Dabe, I considered that a long time ago but wanted the option of using various helmets. The Dynafit Beast helmet, on the other hand, is one of the few out there with MIPS as well as snowsports AND climbing certs. But it’s not imported into North America. Tragic. Other than the Beast not having great ventilation, it appears to be exactly what we’re looking for in a step up in actual protection from TBI. Lou

    I would think a longer chord with the battery pack mounted in the rear waist ala bike jersey pocket would lighten the neck load .

    Unfortunately the Petzl Duo does not have an accessory extension cord, but yeah, with other headlamps that do have a cord extender, getting the battery weight off the head can be quite noticeable. Plus sometimes the batteries need to be kept from cold temps. Black Diamond Icon, for example, comes with a cord extension. Lou

    DNA carbonio helmet is droolworthy in the weight and style categories. Though if I’m ponying up €300 for a helmet I’m thinking it’s gonna be a Sweet Protection.
