The reason we love Troy Lee lids though isn’t just about their style, it’s also about their fit. We always say different heads suit different brands, but there’s not one of us at Dirt that has ever found a helmet that fits better than a Troy Lee.

‘Next time you watch the World Cup Downhill, take a moment to see just how many of the fast boys and girls trust a D3 to look after them if things go nasty’

With a major revamp in 2016, Troy Lee Designs moved the already impressive D3 design forward again. They really have left very little room for improvement and this helmet is crammed full of really well thought through details and our pick here is the top of the range Carbon D3 with added MIPS protection.

A hand laid pre-peg carbon/composite/MCT construction keeps weight low but strength high with a top layer UD (unidirectional) carbon weaves providing added strength and a touch of style. TLD have spent plenty of time in the wind tunnel testing the aerodynamics, honing both the shape and twenty venting ducts to perfection. This all adds to the costs and you start to build up a picture of just what goes into this top end helmet and goes someway to justifying the high price tag.
