Item # GIR00AH

A no-brainer.

Your weekend plans might include pedaling through long, winding climbs, snaking along exposed ridgelines, and flying down wild, challenging descents. If they do, ride with Giro's Montaro MIPS Helmet to protect your control center without weighing yourself down. Designed for long days spent on the trails, the Montaro is constructed with a durable In-Mold polycarbonate shell surrounding an impact-absorbing EPS foam body. MIPS, or Multi Directional Impact Protection System, is added to the innermost layer of the helmet in the form of a thin lining that rotates slightly upon impact to absorb the brain-damaging rotational energy created in certain crashes.

Beyond safety, Giro ensures the Montaro won't slow you down by designing it to integrate with your other riding gear, including a built-in camera mount with a breakaway design to protect you and your device in the event of a crash. Giro's P.O.V. Plus visor adjustment system allows you to reposition the visor to accommodate full goggles, and strap grippers on the back of the helmet help keep the goggles in place. To keep the helmet from feeling cumbersome on hot days and long climbs, Giro created space for 16 vents with internal channeling for efficient air flow. The Montaro is lined with hydrophilic, anti-microbial padding that absorbs sweat and, together with the Roc Loc fit system, provides a comfortable, secure fit.

    Great helmet so far

    I've used it several times
    True to size
    Size Bought

    I like the helmet. The fit is similar to the other Giro helmets I have worn for road, TT and MTB in the past. I have not had it long enough to comment on the longevity of the pads. Ventilation seems OK. The GoPro mount is supposed to be a selling point but it's not quite up to the job. My helmet came without a bolt for the GoPro interface and the mount seems to be a bit fussy about the length of the bolt, standard GoPro mount bolts do not reliably work without adding spacers and even then the mount does not hold the camera steady unless it is severely over-tightened. I had to use a wrench to get it tight enough.

    This helmet's a winner

    I've put it through the wringer

    Really liking my Giro MIPS Montaro helmet and I've worn it on more than 20 rides so far. Ventilation is good, fit is good ; would love it to be a bit lighter weight but I often forget I'm wearing it, which is the best testimonial for any helmet.

    looks great, feels great.

    Go to trail helmet

    This helmet has really impressed me so far. It has great adjustability around the forehead and also has many positions for the visor. Ventilation is excellent, and the finish of the plastic material seems to be semi scratch resistant. Better than helmets I have used in the past, and MIPS protection is always a bonus when playing with gravity.

    Solid helmet!

    I have never used a half-dome helmet but I wanted to invest in one, finally. This has MIPS, which I really wanted, is light and breathable and is pretty comfy. Happy with the purchase. Now to get out and ride with it!

    Great trail helmet

    I've used it several times

    This helmet has great coverage for average trail riding. Very good price for a MIPS helmet to. Pretty breathable but not as much as something like the Forefront.

    I chose the Montaro in the end

    While shopping for a new helmet I actually went into a local bike store to try a few on but found the price on Backcountry to be cheaper. I tried the Montero on while in the store and really liked the way it felt compared with other brands and models. That made buying decision a lot easier. I definitely recommend measuring your head to get the proper size. Size up if you measure at the high end of the recommended size -- it will fit much better

    Sturdy as it comes for a half dome

    I've used it several times

    I've been using this helmet for about a week now and am pretty pleased with how durable it is. No hard crashes yet but with any kind of blow, it's impressive how little you feel it. My only complaint is that it doesn't quite fit 100% perfectly to my head, but overall a very comfortable and durable helmet.


    Any idea if Giro has fixed the problem with the forehead pads? My wife and I have both owned this helmet (her the Montara), and both forehead pads delaminated. Other than that I love the helmet and would buy again. Thus, why I'm wondering....

    I had the exact same issue. Forehead pads completely fell apart in under a year. Giro said they'd send a free replacement set, but unfortunately they are out of them for another 6 weeks...doesn't help too much :/. Any Gearheads have more info??!! thanks

    Didn't Quite Fit

    I bought this as a gift but the fit didn't work. Ending up going with a TLD A2. This looks like a well constructed helmet with nice coverage and venting. If this works for your head shape it is a great option.

    Super Comfortable and Looks Great

    I've used it several times
    True to size

    This helmet fits perfectly, and has no points that poke or prod anywhere. The Roc Loc Air fit system is very easy to adjust and fine tune for the perfect fit. Also, this helmet looks fantastic. I got the Matte Sonic Psych color way and am not disappointed with the looks. The rubber grippers on the back vents hold goggle straps perfectly in place, and the visor flips up with plenty of room store goggles out of the way.

    Looks sweet, good ventilation.

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

    This helmet is pretty sweet. It looks awesome, and has great ventilation. However, make sure you bring your favorite riding shades when you try on the helmet. I could see some having some hot spots around the temples. Love this helmet so far!

    Great Look and Design

    I've used it several times

    Happy with this lightweight helmet, the MIPS technology (extra assurance), style and features included in the design: breathability and adjustability and a cool aerodynamic look for ripping on the mountain trails. Love the Matte Black, but honestly, the color choices made it a bit tough to choose which to go with. Can't go wrong with any of them.

    Great helmet

    I've put it through the wringer

    I couldn’t be happier with this helmet. It fits great, stays cool on hot days, and is excellent when it comes to protection. I recently took a very hard fall and a significant impact to the head/helmet. This helmet prevented things from being much worse. I have had a few concussions from lesser impacts over the years and this helmet out performed my expectations. This helmet is certainly worth the price.

    I am very happy with my purchase of this helmet! It is lightweight, looks great, and wont break the bank.

    Great helmet from Giro

    I've used it several times

    Big fan of this helmet! Fit's great and is super comfortable on head, light weight but still feels strong enough if it ever needs to be used, and it's definitely a good looking helmet.

    I look so cool

    I've used it several times

    stylish, lightweight, super comfy.... this helmet checks all those boxes. I was drawn to this helmet for the "flair" that goes around the base of the helmet. I think its a nice addition to any of the color schemes.

    Comfortable Helmet

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

    This is a very comfortable helmet, and the Matte Blue/Lime colorway is awesome! The GoPro mount is a bear to attach to the helmet, but at least I know my camera won't fall off! I like the Roc Loc Air fit system, but the wheel is smaller than I'm used to which makes it a little harder to tighten. Overall this is a great helmet! My Oakley Flak Jacket sunglasses fut under it great!

    Jeff can you store the sunglasses on your helmet like on road helmets?

    Snug, Comfortable Helmet

    I've used it several times

    I have a 24" head and went with the Large. It fits great. Super snug without squeezing my noggin. It doesn't flop all over the place like helmets I've had in the past. It took maybe 2 mins to get the fit dialed and I haven't touched it since. Really am liking this helmet so far. Happy that I got it!
