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.

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

    • Familiarity: 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

      • Familiarity: I've used it several times
      • Fit: 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.

      • Familiarity: 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

      • Familiarity: 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

      • Familiarity: 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.

      Great Fit

      • Familiarity: I've used it several times

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

      Great helmet from Giro

      • Familiarity: 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

      • Familiarity: 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

      • Familiarity: 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

      • Familiarity: 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!

      Good fit, bad pads

      • Familiarity: I've used it several times

      Helmet fits well, very comfortable. Doesn't interfere with the fit of my Oakley sunglasses. As others have stated, the Velcro liner on the sweat pads is an issue, it began to pull away from the foam after an hour of use. Easy enough to replace or repair, but a very annoying issue on an otherwise great helmet.

      The Perfect Fit

        I purchased the women's version for my wife, I was curious about the fit and feel with the MIPS outfitting, so I tried it on and that's all it took, I ordered one. Right out of the box this is the best fitting helmet I have ever owned, the size(M) is just right for my head shape, no strap adjustment necessary.

        Awesome price for MIPS

        • Familiarity: I gave it as a gift but have feedback to share
        • Fit: True to size

        Breathable, comfortable, and secure.
        I purchased this helmet for my husband for his birthday, and he's digging it big time. The Olive color is an awesome option for someone who likes a more subdued look but is a little bored of black and grey.
        The Giro Montaro MIPS helmet, as the name implies, features Giro's MIPS technology to keep your cranium extra safe from blows you might encounter in all directions. The fit is comfortably and true to size, and the vents are well placed to keep you from overheating.

        Feels Good, Gives Me Headaches

        • Familiarity: I've put it through the wringer

        The helmet feels fine but I found it was giving me headaches (i do not normally get). I set the retention system slightly more loose than other helmets I'm used to wearing and it seemed to have solved the issue.

        Like it so far

        • Familiarity: I've put it through the wringer
        • Fit: True to size

        This helmet has been good for me so far. It fits well, is comfortable, reasonable weight and good ventilation. I really like the blue/lime color that I bought as well. It works well with my sunglasses and sweat bands. In the past I have been either a medium or a large in helmets. In this case I had to size up to the Large. The MIPS shell does take up a few millimeters of room inside the helmet.

        My one complaint is that the pads wore out quickly. The liner peeled away from the pads revealing the foam underneath. Minor issue and replacement pads are cheap but it happened after about 2 months of riding. I do sweat a lot, but it still seemed like premature wear.

        Sweet Helmet

        • Familiarity: I gave it as a gift but have feedback to share

        I purchased this as a birthday gift for my boyfriend and he loves it. Unfortunately he has not had a chance to test this out yet due to the snow on the mountain, but should be able to soon. This being said, I only have fit and initial impressions to offer as feedback. Overall he raves about the fit and look. The large ran true to size, really light weight, tons of ventilation for those hot summer days, and while a little bit more in price the MIPS feature is great. He isn't always good about replacing his helmets when needed so I thought this feature is perfect for providing me with peace of mind. The Matte Vermilion ended up being my color choice since orange is his favorite color. It will also offer high visibility as he tends to ride after work throughout the summer. Overall I think this will be a great addition to him biking gear.

        Simple, Solid, Steezy

        • Familiarity: I've put it through the wringer

        This lid gets the triple S review score. It is extremely comfortable fitting with adjustments available if needed. Great lock design that holds the helmet snug even in the most extreme downhill conditions. Took a pretty hard slam the other day and had no noticeable complaints from the helmet in an impact scenario. It also helps that the color variants are pretty stylish. You also get mips protection for a fraction of the price of a smith forefront for example. Great helmet at a great price.
