    More coverage, more protection.

    Troy Lee Designs doesn’t mess around with gimmicky technologies when it comes to protecting your head — they cover up what can get hurt, carve away spots for air to get through, and add an adjustment system to keep it all tight to your head. The result? The new A-1 Helmet. With a polycarbonate shell over EPS foam, the A-1 will take a beating, even if you hope it never has to. Troy Lee added 16 distinct vents to move air into, over, and out of the helmet, and there’s a synthetic liner with CoolMax pads to assist in moisture management.

    • Multi-position cams for optimal fit
    • Fuller-coverage helmet
    • 16 big vents for airflow

    Great helmet

      Maybe it's because I've used the same helmet for the last 5 years, but this helmet is a huge upgrade. The fit is super snug yet comfortable. Easily can adjust to your head size. Very breathable and light. Also looks good.

      Great fit, super light!

      • Familiarity: I've used it several times

      The A1 Helmet has a great fit, is super light and has a great ventilation. Good compatibility with goggles also which is key for me..The helmet adjustments are easy to use and simple enough..wearing the helmet out on long rides is no issue, can wear it all day..

      Very happy with this purchase.

      • Familiarity: I've used it several times

      This helmet fits true to size. It is very light weight and comfortable. The adjustable head band keeps the helmet in place while riding. So far, I've only worn the helmet in cooler temperatures, 16˚F - 55˚F, and didn't notice my head being either too cold or too warm..... just comfortable. I'm very pleased with this purchase.

      Awesome helmet

      • Familiarity: I've put it through the wringer

      Bought this helmet Spring 2015 and couldn't be happier. It feels like a helmet should, not some bulky piece of foam/plastic on the top of your head. It's been through a couple crashes already and does its job. Also the ventilation is great.
      I've used it on the trails in Northern MN, Montana, and Telluride/ Grand Junction, CO. Highly recommend this product, not the cheapest helmet out there but more than likely your bike isn't a huffy either, so $111.20 isn't bad.

      Great Helmet

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

      I love this helmet. I've tried on numerous helmets and this is by far my favorite. The padding inside makes it one of the most comfortable helmets I've worn. I like how it comes down on the side to protect your temples and comes down in the back. You really feel protected wearing this helmet. I haven't worn it riding in really hot weather, but it seemed to ventilate well on a normal day. I seem to have a hard time finding helmets to fit right ( I have a big head) but the M/L worked great.

      Great MTB helmet

      • Familiarity: I've used it once or twice and have initial impressions
      • Fit: True to size
      • Size Bought: M/L

      I saw a cyclist with this helmet on at a 12 hour MTB race and it looked nice so I asked him about it and he said it was the most comfortable helmet he had ever worn. So I bought one and I agree. I love it. It looks nice, fits well, and I basically forget it is on. The visor comes in handy if you are riding into the sun. I bought the white with black because it matches my bike but that is the only thing I would have done differently--I like the grey with green better. I have only worn it a few times but on long rides over 3 hours.

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

      His review says all you need to know about this helmet. It saved his brain. That dent in his helmet is the result of a VERY hard crash at high speed (I was there). The TLD A1 was up to the task leaving his brain virtually damage free.

      I would like to thank Mr Troy Lee for saving my ass (head). Seriously though, helmet is extraordinarily comfortable and lightweight to boot. I highly recommend this product to all members of the #endurobro(ad) crowd.

      Not Rocket Red ... more orange

      • Familiarity: I returned this product before using it

      This is a great helmet, fits me really well and I'm sure I'll get plenty of use from it ... but it's definitely not the red I thought I was getting. So much more orange than red. The chin strap is almost fluorescent orange. It's going back for a different color.

      The best hemet, really

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

      I seem to have a hard time finding helmets that fit my head. I'm either between sizes, or my head just doesn't fit the shape quite right. I try on helmets every time I go to a bike shop just in case I find the one that feels good. They never do.

      I thought I'd try the A1 after reading nothing but glowing reviews, all of which seem to praise its fit and comfort. Amazingly, everyone is right; this is by far the best fitting, most comfortable, and highest quality mountain bike helmet I've ever worn. I've only used it twice on singletrack so far, but that's enough for me to know that this one is the new benchmark.

      The shape fits my head perfectly, which is amazing because it seems to fit everyone's heads perfectly. The padding really is better than that offered by competitors. Usually, there's a thin amount of padding at only the points where the helmet makes the most contact with your head, usually at the forehead and running up the top . The A1 covers every point of potential contact, and with a pad that's higher quality and more plush than any I've seen elsewhere. After three hours on the trail, I felt no pressure points, no hot spots, and no need to adjust or remove it.

      It also doesn't flop around or shift while riding over rough sections. It just never moved. The dial in the back didn't back off after hours of riding, either. Once I put it on and had it how I wanted it, that's where it stayed until I took it off.

      It also looks awesome, but you don't need a review to tell you that.

      If you're reading this, you probably want the A1 already. I would recommend you forget about the price and try it. It's the most important piece of gear you're going to use, so it's worth a little extra money. If it fits like it seems to fit everyone, you'll very quickly forget about the cost and realize that every other helmet falls in a separate category. I was a skeptic, but if I crack this one tomorrow on the trail, I'll throw down the money for another one without hesitation.

      Awesome helmet!

      • Familiarity: I've put it through the wringer

      I bought this helmet (Orange) a few months ago so I've used it enough (1-4 times a week) to give a review.
      This is the most comfortable helmet I've ever owned. It fits my head shape perfectly (thanks to the nice adjusting system inside the helmet). It's light and I like the extra coverage on the back of the head. This summer was hot (high 80s - 90s ...... hot for Seattle area, WA:) and the helmet ventilated well.

      On top of it all the helmet looks great!

      Awesome helmet!

      SO comfortable

      • Familiarity: I've used it several times

      I swear this is so comfortable, compared to other helmets I've tried. The airflow is great- my head feels fine and isnt sore at the end of long rides. The straps are easy to adjust to be safest, and I love how much of the back of my noggin is protected.

      SO comfortable

      Best helmet I've worn

      • Familiarity: I've put it through the wringer

      This is an awesome helmet! The mold they use fits my oval head perfectly. It's light, no complaints about the strap adjustment, and the airflow is pretty darn good. Best helmet I've worn

      The Best/Most comfortable helmet out.

      I've tried a lot of different helmets but will never stray away from the A1. It's by far the most comfortable helmet I've owned with it's deep sunken fit and it's stylish look why look anywhere else.

      The Best/Most comfortable helmet out.

      Great Helmet

      • Familiarity: I've put it through the wringer

      The A1 is one of the industry-leading helmets for a reason: maximum venting, comfort, affordability and style, all with a pretty sweet selection of colors and sizing.



      I would say that the single drawback to the helmet would be the sweat management -- I've never had a helmet drip sweat down my forehead and directly into my eyes/glasses area like the A1, but it's such a minor flaw that the awesomeness of the helmet is barely diminished. Removeable pads make it easy (really easy!) to keep clean, dial-adjustable sizing makes it a perfect fit for any head shape, and clean, open styling makes you look good, even if you have a weird face (like myself). Some helmets make me look and feel a little like Toadstool from Mario Brothers, but the A1 keeps it low profile. The front brim is a lifesaver on sun-facing rides, and the helmet is so comfortable that I rarely bother taking it off on hike-a-bike sections or between shuttle laps.

      Great Helmet

      I have a 22 inch/57cm head should I get a small or a medium?
      Thanks

      Wife and kids got me the A-1 for Father's Day. They ordered the xl/xxl and my head seems to be swimming in it. My head measures an all most perfect 23". Should I return it for a M/L

      love this helmet. does this A1 matte version come with the protective/storage bag like the other troy lee helmets?

      My head measures just over 23 inches. I'm afraid if it runs small it won't fit. So how true is the sizing? Also how loosely should I be holding the tape measure?

      Hi YETIMAN,



      Yes, the Gold Flake is available as our option 'Gold.' I apologize that the photo is not showing up correctly on the site. It should look as TLD has it on their website. If you have any other questions feel free to let me know, I have the helmet myself as shown by my review below.
