## Customer Reviews

### ⭐⭐⭐⭐⭐ Offers safety; easy to fit & comfortable to wear
*by  on Reviewed in the United States October 18, 2025*

This is a good helmet! It's comfortable & easy to use, fit, & adjust. I love that it has a light for being seen. It's a nice color & a reasonable price. Finally, I feel that it offers a good level of safety & I'm going to dispose of our old helmets. It is lightweight & has ventilation. This new helmet is SO much nicer than the old helmets!

### ⭐⭐⭐⭐⭐ Perfect helmet for the price.
*by  on Reviewed in the United States December 28, 2025*

I have been using this helmet for over 6 months now and its been fantastic. The padding and build quality are excellent, and it has held up really well using it multiple times a week. It also has excellent ventilation, and I feel like my head sweats a lot less in this helmet than previous ones I have owned. I have been lucky enough not to crash to fully test it out, but based on the overall quality, I am certain it is very safe and will perform well. The battery life on the rear light of this helmet is also excellent, and the red lights are very bright. They have performed well when riding at night.This is a great helmet for the price and also looks awesome! Grab this one!

### ⭐⭐⭐⭐ Not quite black
*by  on Reviewed in the United States April 3, 2026*

Overall the helmet is okay. Safety is the most important thing, and I am confident it will do its job well, and it fits good, secure, comfortably. I ordered black but in the sunlight, (which is where I will wear it hopefully) it appears to be very dark blue... not quite black. Also the LED light was a pain to get out. It says no tools required but I had to get out a flat head screw driver, and it felt like the plastic tabs were going to break before it popped out. As you can see from my photo, I think maybe the light wedges too deep into the helmet on the left side. It took a lot of prying and it scuffed up the back of the helmet.
