The Bontrager Rally MIPS Mountain Helmet offers serious performance at a price point that can’t be beat. It’s got tons of great features that will keep you comfortable and protected out on the trail.

Better protection from angled impacts
The MIPS (Multi-directional Impact Protection System) consists of an innovative liner that better absorbs rotational force from angle impacts, which in turn better protects your brain from injury. There’s also more drop-in coverage for extra back of the head protection.

Ridiculously easy fit adjustments
The Boa dial system allows you to make one-handed micro adjustments so you can quickly find the perfect fit, even mid ride.

Camera and light compatibility
If you want to record your ride with a GoPro or clip on a Bontrager light, the Blendr mount system will make accessory attachments easy secure.

Superior ventilation design
The new composite design allows better airflow, which helps cool you down and keep the sweat out of your eyes while you ride.

Crash Replacement Guarantee
If your helmet is involved in a crash within the first year of ownership, Trek will send you a new one for free.
