Troy Lee Designs - A3 Halo MIPS Helmet (MTB)

A3 Halo MIPS Helmet is a Troy Lee Designs mountain bike helmet built for enduro and bike-park riders. The A3 shape suits aggressive trail riding with an emphasis on day-long comfort and modern mountain bike coverage. It is shaped around dependable protection, ride comfort, and the clean finish Troy Lee Designs helmets are known for. The Halo treatment gives this helmet a more individual feel than a plain solid option. The MIPS-equipped build adds another layer of confidence for riders who prioritize modern helmet technology.

That combination of coverage and ventilation makes it a natural match for riders who move between trail networks, rocky descents, and bike-park days through the season.

Why We Like It: it gives riders a stable feel on rough descents without turning every climb into a chore.

Why It’ll Work for You: It works well for riders who split time between trail loops, enduro stages, and lift-served laps and want one mountain bike helmet that feels ready for all of it.

Variants / Options: multiple sizes and colorways available; check the selector for current stock.
