The all-new Bluegrass Jetro is designed to have fun in the dirt for riders or e-mountain bikers aiming to push further. The Jetro has a 3/4 structure with a distinctive design inspired by the Vanguard, ensuring full protection on the back of the head and jaw, thanks to the EPS shell that extends over the entire coverage of the helmet. The construction of the Jetro is engineered to exceed NTA (speed Ebike certification) and rotational impact testing standards such as MIPS and Virginia Tech Protocol, where it’s ranked as the safest MTB helmet. Stable, comfortable, and secure, this helmet blends cutting-edge technology with sleek design, providing riders with the perfect option that falls between a full-face and an open-face model.

“I like it because it’s the perfect mix between a full face and a classic open face. That’s the ideal helmet for enduro or E-bike rides, those long rides when you push your pace more than usual. But it’s also perfect to ride in Dirt or Slope with the friends. I can do pretty much everything with this helmet, while being super stylish!"


“Since I got the first prototype, I just keep using it all the time in E-bike, Enduro and Dirt. I love the style and I feel way more protected than in an open face. It’s my daily helmet!”


“I have the feeling to wear the perfect helmet between a full face and an open face. It’s clearly the helmet I will use most from now on. I feel light and safe. I will use it mostly in E-bike, enduro, but also in Dirt."
