Construction & Safety Features

The Smith Triad helmet is built with serious protection in mind. It uses Zonal Koroyd®—a lightweight material that absorbs energy during crashes. This helps reduce the risk of head injury without making the helmet bulky. It also features MIPS® (Multi-directional Impact Protection System), which reduces rotational forces during angled impacts.

Some versions of the Triad include the Aleck Crash Sensor, which sends your location to emergency contacts if it detects a crash. Inside the helmet, the Integrated Skeletal Structure adds strength, acting like a roll cage to keep you safer in hard impacts.

Fit & Comfort

Getting the right fit is simple with the VaporFit™ Dial Adjustment System. This system wraps 270 degrees around your head and adjusts easily with a dial at the back. It gives you a secure, custom fit every time. The helmet also includes an Ionic+® antimicrobial lining that controls odor and keeps things fresh even after sweaty rides. At about 290 grams (medium size), the helmet feels light and comfortable for long periods of wear.

Ventilation & Eyewear Integration

With 19 fixed vents, this helmet keeps your head cool. Air flows smoothly through the AirEvac™ Ventilation System, which also works with Smith eyewear to reduce fogging. The helmet includes special front and rear channels for storing sunglasses when you’re not wearing them. This keeps your glasses secure and handy, without needing an extra case.

Design & Variants

The Triad MIPS comes in a range of matte colors, including a limited-edition matte black with a topographic print for the Aleck version. Sizes go from Small to Extra Large, so most riders will find a good fit. The design is sleek and modern, aimed at cyclists who care about performance and style.

Road Cycling and Gravel Biking

This helmet is designed for serious cyclists. It’s great for gravel biking and road cycling enthusiasts who want strong protection, great fit, and modern features. Whether you’re training, racing, or doing long weekend rides, the Triad MIPS fits the bill. It suits both casual and competitive riders looking for comfort and safety.
