A masterpiece of versatility.

It's been a while since the folks at Troy Lee Designs designed and built an all-mountain helmet. As is always the case with TLD, they came out with a bang. The A-1 Helmet is a definite departure from the Troy Lee norm, but it's built with TLD's legendary attention to detail and durability.

The first thing you notice about the A-1 is its sculpted, almost artistic shape. More than simple aesthetics, the shape of the A-1 increases air flow through the helmet to keep your head dry and cool. This is especially important when you're grinding out a punishing climb in the heat of the summer. Airflow is directed through 16 cooling vents–6 intake, 4 multi-directional, and 6 output vents. The shape of the visor, which can be adjusted a full inch on the fly, was also dictated by airflow. Moisture management is assisted by a nanowick synthetic liner with CoolMax panels.

The durable polycarbonate shell surrounds single-impact EPS foam for light weight and proven protection. The visor is made with high-impact polypropylene for additional eye protection. Troy Lee used super-durable anodized aluminum hardware throughout the A-1's construction. The A-1's customizable fit is taken care of by triple-position stabilizer baskets and a multi-position cam-lock adjustable stabilizer with +/- 20mm of movement.

The Troy Lee Designs A-1 Helmet comes in three sizes: XS/S, M/L, and XL/XXL. It is available in Gold and Black.

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

hot and heavy

  • Familiarity: I've put it through the wringer

The A1 is comfortable, stylish, and feels like it would be great in a crash, but it is hot and heavy. I have one sitting in my gear bag right now; it might see some more action this fall and winter.

Love This Helmet

  • Familiarity: I've put it through the wringer

There's a reason you see so many of these on the trail; it's a comfortable, well-designed helmet and one of the best looking on the market. The A-1 offers plenty of coverage, protecting the side and rear of your noggin, while still maintaining a low profile so you don't look like a mushroom. The cinch system is spot-on, using a small dial that can be easily adjusted with one hand while riding. You can get this thing snug. This is not the most ventilated helmet I've ever owned, even in white I found myself sweating more than in my previous 661 Recon. I'd attribute that to the increased coverage the A-1 has, but just something to be aware of.

Thank you troy lee!

  • Familiarity: I've put it through the wringer

What can i say this is the best helmet on the market. You dont believe me look below. 15 feet to my head and i walked away with just a bruised shoulder. Every other helmet i have tried just doesn't fit as well as this one. Its coverage is perfect and the protection is unmatched. I also really enjoy the 16 vents as they do a great job keeping you cool on the trail. it also weighs nothing so if you arent getting this helmet you are missing out. The real question is if you want to go MIPS or non MIPS. If you have any questions or need help with sizing reach out anytime!!

Thank you troy lee!

It's the A1, nothing more to say

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

It's the A1, what else can I say? It's one of the best trail helmets on the market, tired and true for the past several years. Plenty of cool colors to choose from. The padding and shape of the helmet makes it very comfortable. It's lightweight and well-ventilated. You really can't go wrong with this helmet considering others cost twice as much or more.

My head measures about 23 inches, so sort of in between M/L and XL/XXL.. should I go with the M/L? I dont want it bouncing around but I also obviously don't want it too small

Hi Ben,



I would always error on the small side with something like this. Better off having the helmet all the way opened up as opposed to totally cranked down. If the size you decide to go with doesn't work, let me know and I can help you out with an exchange. Feel free to reach out with any other questions. - Matthew Pizza - Expert Gearhead

Super Comfortable

  • Familiarity: I've put it through the wringer

Fits snug to my dome and is lightweight. Only thing I don't like are the straps. I haven't yet found a way to get them to fit perfectly.

The Most Comfortable Helmet Ever

  • Familiarity: I've put it through the wringer
  • Fit: True to size
  • Size Bought: M/L

This is the most comfortable half shell ever. Apart from feeling like a ball cap, it breathes great, and has the rad troy lee styling. Some of the colors are a little over the top, but you can get the drone edition. I have also crashed really bad, and I am still here, so more evidence that it rocks.

Stellar Half Shell

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

Lets face it , half shells can look and feel a bit terrible. The Troy Lee A1 however does not disappoint. Not only in my opinion does it look great but it also performs incredible.

It is very comfortable and does not have any pressure points or uncomfortable spots at all. Worth every penny.

I have not found this helmet unusually warm at all.

please email me at rlogan@backcountry.com for any additional insight.

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.

    Light and Airy

    • Familiarity: I've used it several times

    Extremely comfortable and very light. Lots of vents to let plenty of air through. Peace of mind knowing your dome is well protected. Looks great too!

    Light and Airy

    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.
