It may look XC but it's so much more than that, it's the A2 from Troy Lee Designs

Think bike, think helmet, right? We think so and you’d certainly not see us out on the trails without a suitable lid so, with that, we’ve been testing out some of the best MTB helmets on the market, starting with the Troy Lee Designs A2 MTB Helmet.

Buying guide: MTB helmets

Troy Lee Designs has long been a supporter of women in mountain biking and were one of the few brands to cater for women when no one else would. Last year, we were pretty stoked on their trail collection, and so, expectations were high when we got the A2 lid strapped on.

Troy Lee Designs A2 MTB Helmet

This helmet is packed with features to protect your noggin;

There’s a 25% increase in air-flow from its predecessor, the A1 – odour control and moisture wicking liner – Dual Density EPS co-moulded with EPP with more protection in the frontal lobe – reinforced polycarbonate shell – rear stabilizing fit with three visor positions.

It’s hard to believe all these safety-queen features pack so neatly and efficiently into such a low profile and slim shape. Expanded polystyrene (EPS) is your more common helmet material and Troy Lee Designs has combined this with EPP, a softer material for low-velocity impacts providing even more protection.

The Troy Lee Designs A2 MTB Helmet may look quite XC in many ways with its low-profile and huge air-sucking vents, but this lid is extremely versatile making it ideal for all disciplines of off-road adventuring.

Not one to shy away from bold colours and patterns, Troy Lee Designs has developed a huge range of colours to choose from with the A2, so you’re guaranteed to find one to suit your style.


The A2 MTB helmet breathes fresh air into mountain biking, literally. The vented visor and lid channelled air throughout, a much-welcomed feel when gunning it on the climbs.

Despite having a low-profile and being rather slimmer than the A1 model, the coverage still felt adequate and secure, especially confident inspiring when fastened up with the rear retention system.

On a personal note, I felt the shape didn’t quite suit the shape of my head as a pinching pressure crept its way in after some time on the bike, along with a slight teetering effect which I used extra padding to balance out.
