Big lines.

If you've got a weekend in the desert and some Semenuk-inspired tricks you're itching to try, don't cut corners on your lid. Giro's brand new Switchblade MIPS Helmet encourages you and your DH monster to get rowdy and send it when you're out on slickrock, but it also backs you up with full face coverage, a removable chin guard, and the added protection of MIPS to help you stay safe when you crash hard.

Not every weekend involves staring down do-or-die lines, which is why Giro made the Switchblade's chinbar removable. Snap it off quickly before you head out on a mellower trail ride and enjoy added ventilation from Giro's Wind Tunnel design, included specifically to provide as much airflow as possible on hot, sunny climbs. Giro's tried-and-true Roc Loc Air fit system makes an appearance on the Switchblade as well, but it comes tweaked to DH standards with a bumper protecting the dial from being unintentionally moved when it comes into contact with your pack or body armor.

It's hard to believe that MIPS was a little-known technology just a few years ago, as the thin inner basket has become a ubiquitous option in the world of helmets. Giro doesn't mess around with the Switchblade, including the rotating inner liner to absorb the brain-damaging rotational energy created in certain crashes without compromising the helmet's lightness. Whether you've got the chinbar on or not, the Switchblade exceeds safety standards from all major governing bodies. If you're taking a break from POV coverage on a training ride, swap the visor with the integrated mount for the other visor without it; Giro ships the Switchblade with two separate visors to cut down on the risk of unused mounts adding weight and causing injury in crashes.

  • Sit back and send it with this full-face helmet as backup
  • Removable chinbar adds extra protection on big lines
  • MIPS protection limits brain-damaging forces in some crashes
  • Two visors let you ride with or without a camera mount
  • 20 vents plus Wind Tunnel ventilation keep the air moving
  • Odor-resistant padding keeps things comfortable

pretty cool helmet

    best helmet in the game with a removable chin bar, I am a full face helmet guy all the way and really hate open face when I am actually riding, having the ability to keep the open face for climbing and pup the chin bar off to take a few huge breaths is awesome. runs a bit larger than other brand helmets but they only do s/m/l rather than xs-xxl.

    switch hitter

    • Familiarity: I've used it once or twice and have initial impressions

    Let me start off by saying I really like Giro helmets. For skiing and cycling there fit and quality have been great and withstood the tests of time. The Switchblade is a bit of an odd ball for me, I like the concept but part of me thinks if you can just wear a regular fullface or an open face trail helmet. Getting the helmet over your ears is a very tight fit, unless you spread out the shell by pulling on the chin straps. In my opinion the chinbar is angled too far down exposing a large portion of my face. If I were to take a bad digger I fell like the chin bar would not protect my face and simply deflect out of the way. Adjustment on the back of the helmet works pretty well to tighten/loosen the padding. I think for some select riders this helmet is a great option especially if you want to have just one helmet in the quiver to go along with your one AM bike. If you are a rider who has a quiver of trail bikes, AM, DH and DJ i'd say just get a dedicated trail helmet and a dedicated fullface.

    Nice Helmet, Not Best Fit for Me

    • Familiarity: I returned this product before using it

    The overall quality and tech of this helmet appears very high but I couldn't get the right fit. I tried both a medium and a large at 59 cm / 23.25 inches, which is right on the line. I have a wider jaw and longer face which made the medium a bit too snug on the cheeks (and chinbar too high) despite the actual head fit feeling OK. The large was workable but I had to tighten down the adjuster almost all the way and it felt pretty big. The chin bar system seems pretty well designed if you want to go removable. I had been deciding between this and the Fox Proframe and I will end up going with Fox as my fit was better when I tried it on (L) and the design was killer. I did not need the removable chinbar of the Switchblade but thought it was cool to explore anyway.

    All mountain helmet

    • Familiarity: I've put it through the wringer

    I was looking for a helmet that would come up with me on the climb up and be good for going down some gnarly trails and I found this. I have pretty much gotten rid of my old helmet and strictly use this. It comes with me on park days and trail rides. It does get hot climbing up, but not too bad. It makes me feel more comfortable going downhill and looks great. It is easy to use and I would definitely recommend it to the gnarlier trail riders out there (and downhillers).

    Full face when you want it!!!

    • Familiarity: I've put it through the wringer

    Throw the chin guard in your backpack and head up the mountain, then you're not suffocating yourself when you're climbing up to the top of the peaks.
    Once you get to the top slap your chin guard on and you have full faced protection for the decent.
    This helmet is lightweight and breaths very well via the many vents.
    I wouldn't trade this helmet for any other helmet. It's awesome.

    Convertible Protection for Ups and Downs

    • Familiarity: I've used it several times

    have used the giro switchblade as an option since it was introduced in the late 1990's. this is a great upgrade and with the MIPS system, this is the best one yet. this MIPS system doesn't seem to wiggle. and having the option to lift the visor way up to store your goggles underneath and out of the way should be required on all helmets with visors. this is a great feature! you can stay cool on the ascent and have the protection on the descent. it is very light and fits as i would have expected from my other giro model helmets. the cheek pads are snug but it actually comes with optional sizes. thank you. my smith squad mtb goggles fit but don't seem to have the same profile as the opening. maybe i should get some giro goggles for better air movement? it also comes with a soft pouch for storage and an optional gopro visor. i kind of wish the gopro mount was like the old cipher style. it is easier to deal with that switching visors. oh well, you get an extra visors for any unexpected over the bars action...

    • Fit: True to size
    • Size Bought: Small

    So I was back and forth on how I felt about this helmet but after trying it on and getting a chance to ride around I am really happy to add it to my helmet quiver. It won't replace my every day half shell however there are so many times while traveling or out riding where I want the breathing room of an open face helmet but the security of knowing that it still has downhill capabilities. I think it will allow for some minimalist packing trips as well.

    Nice helmet

    • Familiarity: I returned this product before using it
