Trek Rally WaveCel Mountain Bike Helmet

WaveCel is a collapsible cellular structure that lines the inside of the helmet. Unlike traditional EPS foam, which is designed to absorb impact by crushing, WaveCel material flexes, crinkles, and glides to redirect energy away from your head during an impact.

Yes, the 3-position visor is designed to be pushed up high enough to accommodate goggles when you aren't wearing them. It also features a dedicated storage spot for sunglasses if you prefer to ride without goggles.

The Fidlock magnetic buckle is designed for one-handed operation. It snaps into place automatically using magnets and slides to release, making it much easier to secure or remove while wearing full-finger mountain bike gloves compared to a traditional plastic clip.

The integrated mount is designed to work with most standard action camera and light systems that use a common GoPro-style interface. It provides a secure, centered attachment point that is more stable than adhesive mounts.

While the helmet offers more coverage at the back of the head for added safety, it is engineered with deep internal channels that promote airflow. You will get more protection than a standard road helmet, but the airflow channels are specifically placed to keep air moving across your scalp.

This helmet uses the BOA Fit System, which allows for precise, micro-adjustments to the tension around your head. It is highly effective at eliminating pressure points and ensuring the helmet stays stable during aggressive, bumpy rides.
