Smith Optics has become an icon for its stellar lineup of killer shades, snow helmets, and goggles. But the boys in Sun Valley spend most of the year riding mountain bikes on the region’s countless miles of singletrack, and they (understandably) want to keep their domes comfortable and protected during the warmer months as well. Enter the Forefront Helmet, which pools Smith's extensive knowledge of all things lid-related to bring feather-light construction and hard-hitting protection to your time on the trail.

Smith accomplishes a blend of minimal weight and maximum protection through the use of its patented Aerocore technology. This construction employs Koroyd material, which looks a lot like the bundles of straws you may have used in science class to protect eggs when you dropped them off a roof. That resemblance isn't a coincidence, as this honeycomb construction yields a claimed 30% reduction in forces transmitted to your noggin when compared to EPS foam, the industry standard. It’s particularly useful for building helmets because it requires a minimal amount of material, so there’s no unnecessary weight. It also has the desirable effect of maximizing airflow, keeping you cool when you’re working hard.

The helmet's interior features an X-Static lining with Reactive Cooling Performance to help manage odor and keep you cool. Fit tuning is handled by Smith’s VaporFit retention system, which utilizes a click-wheel adjuster that’s borrowed from Smith's well-tested snow helmet division, so you know it’s solid. The AirEvac ventilation system, which channels hot air out of the tops of your glasses or goggles to reduce fogging, is another import from the snow program.

While the Aerocore construction has plenty of advantages, unrestricted, large vents for clamping attachments isn’t one of them, which is why Smith includes integrated camera and light mounts. Using a threaded brass insert atop the helmet, you’re able to pick up an aftermarket mounting kit with custom mounts for your POV camera or light. While it does require accessories, the upshot is that the mounts are far more secure than the standard strap mounts used to attach those items to other helmets, and the benefit is immediately clear when your POV footage becomes a lot less shaky.

  • Lightweight protection with a unique style
  • Karoyd material reduces force transmission
  • X-Static lining with Reactive Cooling Performance
  • VaporFit retention system adjust easily on the fly
  • AerEvac ventilation provides cooling airflow
  • Integrated camera and light mounts

Mean Green Head Protectin' Machine!

  • Familiarity: I've put it through the wringer

This helmet is rad. Super ventilated, fits EXTREMELY well, and the honey comb design helps to keep bugs out while riding! And if that's not enough to make you want to wear it on a good shralpin' sesh, how about the fact that it looks super pro?! That autta do it for you! Protect your noggin' from a good floggin' with this guy, you won't regret it!

Fits like a glove...I mean helmet

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

My new favorite. Fits great and isn't overly bulky like some helmets are. Very lightweight and well constructed all throughout. Plus 50% off?! Thanks Backcountry.

Excellent Helmet

  • Familiarity: I've used it several times

I was a little concerned that this helmet wouldn't breath as well as some of the helmets that have large open vents. The honeycomb design works very well. It is plenty cool and feels much more solid than other helmets I've owned.

Best in the game!

  • Familiarity: I've put it through the wringer

Love this helmet. The fit is great, the dial on the back really gets you into a snug fit. The airflow is awesome and my head has never been too hot, even on the steep trails. Plus it's a great looking helmet compared to some others out there. Way hyped on my purchase!

Smith Forefront Helmet

  • Familiarity: I've used it several times
  • Fit: True to size

I purchased the Smith Forefront helmet several weeks ago. First it fits well. The sizing dial on the back is easy to adjust on the fly. Secondly its designed for excellent air flow. The honeycomb pattern and horizontal slit design allows air to flow into the helmet keeping my head nice and cool even when the temperatures are in the mid-eighties. Third, I like the looks. I have the camo helmet and it looks really good. Fourth: I like the head coverage. The helmet extends back providing great protection all around my head. I can't quantify how much I love my head. Fifth: The helmet is very comfortable. It stays secure on my head, it has great cushioning inside, and is lightweight. Sixth: Attention to detail. This helmet looks quality. It looks like this helmet will last a long-time and is made from quality materials. Seventh: The straps work well and are easy to adjust. Eighth: I can wear sun glasses with this helmet. I've ridden with my prescription and sunglasses without bumping or scraping. Negatives: None.
Bottom line: I love this helmet and recommend it to anyone that wants a quality helmet. Its a little pricey, but I wear a helmet every time I ride my bike. The helmet is in full contact with my head 100% of the time. You can skimp on some components, but not the helmet. I recommend buying this helmet and I believe you won't be disappointed.

Lightweight and Comfy

  • Fit: True to size

This is a great helmet at the price point. Lightweight on your head with plenty of venting to keep you cool.

Just Awesome

  • Familiarity: I've put it through the wringer

I love this helmet. LOVE.

Got the bright orange because I commute and have to ride roads a decent amount each week, and I really feel like it stands out and makes me more noticeable. I have zero proof of this effect, other than never having been hit by a car, which is my ultimate goal.

Secondarily, orange looks pretty sick in pictures. Living here in the mountains, we get a lot of blue sky. You know what contrasts perfectly with blue? Orange. Boom. You're welcome.

Looks sweet, gets you noticed, breathes well.


  • Familiarity: I've used it several times

Are you looking for a headpiece with a tough outer shell, smooth breathability, and flawless adjustability? If you answered “yes” to any of those questions then STOP READING and get you a Smith Forefront Helmet. If you still have reservations, “ohhh I don’t know, my Bell helmet from the 80s works just fine.” Or “ohhh I don’t know if I can justify the cost.” Also STOP READING, cuz I’m mad at you…I’m sorry, I just get worked up about these things, but really, this is a great helmet, the Aerocore (refrigerator tech) technology keeps your head as cool as...I’m running out of ‘cool’ metaphors.

In the end, it’s an expensive helmet, but it’s a really good helmet. It looks good, it works well, and I recommend it.

Great Fit and Function

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

After trying several helmets we settled on this Forefront from Smith. It is light and breathable.

Lightweight and great fit!

  • Familiarity: I've put it through the wringer

This helmet rocks. The VaporFit adjustments allows for the perfect fit on this helmet and the AirVac ventilation ensures that your noggin never gets too warm! I also love all of the awesome color options that this helmet comes in. And, the integration with Smith biking glasses is a nice addition so that when you take your glasses off, they fit snugly off your face on your helmet, even while still riding!

Great Helmet

  • Familiarity: I've put it through the wringer

This helmet is rad! Bought this one to replace my Rudy Project and the fit is phenomenal! Lots of airflow and super comfortable!

Comfy, light, and looks good too.

  • Familiarity: I've put it through the wringer

Awesome helmet. I started with a cheaper helmet off the bat. I always saw tons of people with this helmet and figured there must be something to that. I got one and have never looked back. Different brands will fit different people but this is one of the most comfy helmets I have worn. The Aerocore technology keeps the helmet super light and breathable without looking too crazy with a bunch of vents.

Highly recommend.

Love this helmet

  • Familiarity: I've used it several times

Growing up, my mom always made me wear a helmet, which I of course hated. Now that I'm an adult, I know why she enforced this rule, but I still hate the sweaty head, lack of visibility, and extra weight. Fortunately, with this helmet, I'm offered all the same safety (and more!), but don't have to deal with any of the downsides. The airflow is incredible, it's super lightweight, and the adjustable visor provides visibility even when grinding away on a steep hill.

If you're on the edge of a size range, definitely size up!

breathe easy

  • Familiarity: I've used it several times

great venting and paired up with some of the best safety makes for one of the best mountain bike helmets on the market. its even comfortable to boot!

excellent helmet

    Iv'e only had the forefront for about one month and I can say it's the lightest and most comfortable helmet and most $$$ I've had to date. Once on you don't even know your wearing it. Today I took a rather slow but high fall from a 3' ledge and got caught up. The bike let go and I fell straight down and hit the back my head. There was a very loud to me bang but i was fine. the Karoyd separated from the shell and the adjustment straps pulled out of the helmet but i am fine. I really appreciated the lower head coverage and called Backcountry to order a replacement they were able to offer me a discount on the new helmet as i purchased the damaged helmet from them. It is expensive but in feel it was worth it. A helmet with this lower head coverage I feel saved me from serious injury . thanks Smith and Backcountry. I understand helmets should be replaced after a big hit and I'm alittle suprised with the level of damage in such a slow speed fall but this helmet did it's job.

    Protect yourself

    • Familiarity: I've put it through the wringer

    This helmet is simply perfect; light as a feather, great retention system to keep it tight, and well ventilated.

    Protect yourself

    Light and Comfortable

      Lightest and most comfortable helmet I've owned. Other helmets have bothered my head after a long ride, but the system to tighten it down is perfect. Works well with my smith glasses too.
