Review on 🚲 Giro Trella MIPS Urban Cycling Helmet - Ideal for Adults by Fritz Wiest

On the positive side this helmet is light and comfortable. That's why it didn't work for me. The round dial on the back is difficult to reach. The top half of the grip is behind the plastic of the helmet, so you can't grab it with two fingers. As the grip becomes stiffer when the helmet is put on, it becomes difficult to turn the dial with just your thumb. I was able to slip my finger under the plastic to get a better grip, but it was a tight and uncomfortable grip. I also found the chin lock to be a bit difficult to unlock for some reason. I had to work on that several times. Maybe it was that particular helmet.
