Giro Trinity Helmet

Safe and simple.

With so many helmets to choose from, how do you know what you are really getting? The Giro Trinity Helmet is a simply engineered design to keep your head protected and cool. The Trinity was constructed using Giro’s In-Mold technology. This process fuses the shell with the EPS foam body to provide structural integrity. In addition, it also means that it is better capable of absorbing impact, should you happen to hit the pavement. The helmet itself features 22 large vents that help to move air over your head to evaporate sweat and keep you cool. And because a helmet does you absolutely no good if it doesn’t stay on your head, Giro uses its Acu Dial fit system to secure it. Reflective accents have been added to the rear to make you more visible in low-light conditions.

Love this helmet, fits well.

    I got this helmet for my 9 and 10 year old kids as they were outgrowing their Giro youth helmets. This fits them perfectly, the adjusting mechanism was easy to use, and the style looks great on too. Got the black with white, the white with silver also looks nice. The helmet also fits well if you need an Asian Fit helmet. We also tried a higher priced helmet and the Giro Trinity still came out the winner by far!

    Great helmet and fits well

    I got this helmet for my two kids, 9 and 10 yo as they were starting to outgrow their Giro youth helmets. The Trinity fit both of them well, very comfortable and looked great too. One of my kids has a slightly flat head and usually needs an Asian Fit snow helmet, since I couldn't find an Asian Fit bike helmet, we tried this one and this was perfect on her as well! The colours are exactly as pictured, we love both the black with white, and the white with silver.

    picture is deceiving

      Purchased the white w/ grey flowers style, as the picture made it out to look mostly white. It's definitely a silver-on-silver style. Will be returning for a true white helmet.

      Good budget-priced helmet

      When you break it down to brass tacks, the primary purpose of a helmet is to protect your melon. Sure, there are helmets that are more expensive, ligher, vent better and look more badass, but if your main care is shielding the ol' noggin, the Giro Trinity helmet does that very well, and at a reasonable price. The Acu Dial fit system adjusts to fit a wide range of head sizes, and the vents do a reasonably good job at promoting airflow to keep you cool.

      Poor finish

      • Familiarity: I returned this product before using it

      The price, fit, weight, and hi-viz were great. The finish was poor. I'm sure it didn't affect protection, but even at a low price point I expect better. This was my second attempt at ordering a Trinity and they were both of similar quality. The vent holes looked like they were whittled out with a pocket knife.

      Helment is very light and comfortable. I recommend this purchase to anyone who is looking for great helmet.
