Item # TLD0273

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

Here's what others have to say...

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.

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.

Best bike helmet you could want

This is the most comfortable bike helmet I have ever worn! It has thick, non obtrusive padding with lots of adjustability. It's also light, and is aesthetically pleasing. What more can you ask for?

None Better

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

I have owned a number of bike helmets having used one for 25 years or so. My current road helmet is a very nice Specialized and my previous MTB helmet was the same. I needed to replace it after I cracked it in an accident (did its job) so I ordered a well reviewed helmet, which was unfortunately painful to wear. I had read reviews of the Troy Lee helmet and one said "Don't put it on unless you are willing to pay the high price." I decided to try one. The review was right. I have never seen such a well made, well fitting helmet. The comfort and fit is well beyond any helmet I have ever worn. My head and comfort is worth the price. I can't see ever buying anything other than a Troy Lee.

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

Responded on

Hey Tea! Thanks for your question.

Since you are right in-between sizes I would recommend going with a M/L size since this helmet has multiple adjustments to make it fit just right on your head.

Feel free to chat or call one of our expert gearheads for any other questions.

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

Responded on

Todd, I would definitely try out the M/L seems like a better fit for you!

Incredible fit!

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

I can hardly believe how comfortable this helmet is, WOW. The second I placed it on my head I realized why it has such rave reviews. My head measures exactly 59 cm and the M/L is perfect, I'm not even at the max range for size adjustment. Highly recommended.

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

Responded on

Hi Tahnee,

The Drone color options for $139 do not include a helmet bag, whereas the more expensive versions include it.

Fit is awesome!

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

Get it, your search is over.

Well Ventilated

Good ventilation. My last helmet was a Bell Super and the Troy Lee is not nearly as hot while climbing. The white on the visor and helmet do not completely match up so if you are uptight about true color match you may look elsewhere.

Good Fit, Great Looks

  • Familiarity: I've put it through the wringer

This helmet fits fantastic for my head (roundish profile). It is comfortable and vents well. The strap system is easy to adjust and the chin strap is looped at the end so you don't have two tails dangling in the wind. The anodized visor bolts are a nice finishing touch. As a bonus Oakley Jawbone glasses fit in the vents so you can post up your glasses when climbing. One minor detail is that the white visor does not completely match the white on the helmet.

Best helmet ever

  • Familiarity: I've put it through the wringer

So, the A1 is really comfortable, nice coverage, pretty much what everyone else said. Unfortunately, I did have the opportunity to use it. Rain washed the trail away from sight, had a bout a 10 foot drop that you really couldn't see. Went OTB at 15 mph and flew head first into a boulder. Visor smacked me in the nose when it broke off, fractured my nose, fractured and dislocated several fingers that went along with the superman I performed. Ended up at the hospital. The ER doc asked what I was wearing, told them about the helmet, gloves etc.. Their comment was that I was extremely lucky to be coming in with what I had based on the trauma I was going thru. They have seen worse injuries with less impact and directly attributed it to the protective gear. The helmet was still intact, albiet it had a few good dents in from the rock garden I landed it, glasses were shot and all scrapped up, but that's what you get those Oakleys for.

No concussion, so I was lucky and the ER Doc attributed it to the helmet.

Look Good, Feel Good, SEND IT!

  • Familiarity: I've put it through the wringer

TLD took their time and didn't overlook any detail when they designed this helmet and that is very evident once you try it on. The adjustments allow you to perfectly fit the helmet to your head This process is easily accomplished via a dial on the back and the straps. Once they are set they wont accidentally change as i have had happen on other helmets.

With added coverage on the rear and sides this helmet inspires confidence inspiring as if you were wearing a full face. While the helmet is not the lightest helmet on the market it is still perfect for all types of riding. The numerous vents flush the hot air out and keep your head cool on hot days. The vent configuration also allows for easy mounting of gopro's and night lights or even sunglasses during a ride.

The visor has never caused any sight issues and can also be adjusted to your liking. Another nice touch is the anodized aluminum visor bolts.

Solid Lid

  • Familiarity: I've put it through the wringer

This is a very nice helmet, as you would expect from TLD. I had a POC trabec before this, which I was happy with, but the fit was off just a little bit. This thing feels like it was custom made for my dome. Went with the turbo orange so I would not be mistaken for a deer in the fall/winter months.

Awsome

  • Familiarity: I've used it several times

Very good quality, very good fit! A litle bit heavier than the usual cross country helmet, but is the price of extra brain protection! Very good price, cheap for the quality that you buy! Very good confort!

Great Helmet

I've owned Specialized, Fox and Giro helmets. This is the best fitting most comfortable of them all. Even leave it on to climb.

Outstanding piece of equipment

  • Familiarity: I've used it several times

I upgraded my lid this year for our vacation to the mountains after taking a few falls recently. This helmet is AWESOME. I felt very secure with it on. I have a slightly odd shape head that usually pushes me to a slightly larger and ultimately less potentially effective size. This locked down onto my noggin no problems and was very cool and comfortable.

My head measures just over 23 inches. I'm...

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?

Best Answer Responded on

Hold the tape measure with the same tightness you want out of your helmet. Most people get the best fit from a helmet 1-2 cm bigger than their head size. If your head is 23 inches/58.5 cm, the M/L should be a great fit.
