Available to view online and in-store today!


The A1 and A2 helmets have made their mark on the mountain bike world, with each iteration bringing better safety, comfort and ventilation. Clearly busy behind the scenes, Troy Lee Designs took the last four years to build on everything that made the A2 great.

The A3 could be the most comfortable premium helmet to date.

Safety First

Safety is front and centre with the Troy Lee Designs A3 Helmet. Co-moulded EPP and EPS foams deliver equal protection across high and low-speed impacts.

The A3 uses B-Series MIPS Rotational Brain Protection technology to offer the best available security from impacts. The helmet retention cradle has now been fully integrated into the MIPS liner. This creates an optimal 360-degree fit that maximizes the safety of the A3 and your comfort. The Troy Lee Designs A3 Helmet also extends lower than previous TLD helmets, to offer best-in-class coverage to protect on even the sketchiest of descents.

Troy Lee Designs obsessed over every detail with the A3. The adjustable 3-Way Magnajust® Visor has goggle storage and attaches in three positions with magnets, so it is easy to move as well as avoiding any small parts breaking. TLD has ensured the helmet works with a vast array of optics making it a great choice for riders, regardless of eyewear choice. The helmet also closes with a V2 Fidlock-Magnetic Buckle for easy on and off.

All these safety precautions have resulted in the Troy Lee Designs A3 Helmet receiving the highest possible score (5-STAR) from the Virginia Tech helmet safety lab, so you can feel confident in all conditions.


This focus on safety doesn’t mean a lack of style or comfort. The Troy Lee Designs A3 Helmet uses the TLD Sweat Glide System – EVA wicking foam behind the comfort liner along the front brow directs sweat away from the eyes and optics, helping to keep your vision clear on the trails.

“You won’t ever want to take it off!”

The 16 vents of the A3 Helmet have been optimally tuned with the channelling of the helmet to create the most intake and exhaust of any half shell helmet Troy Lee Designs have ever produced.

Available now in several striking colourways, the Troy Lee Designs A3 Helmet displays how TLD continue to set the standard in mountain bike helmets, whilst retaining the classic style they’re known for.
