Helmet Size Guide
How to Measure Your Head for the Perfect Fit
To ensure the most accurate fit, follow these steps:
- Use a measuring tape and wrap it around your head as shown in the image.
- Measure above your ears, from the forehead (just above your eyebrows) to the back of your head, and back to the forehead.
- Compare your measurement with the helmet size chart to find your ideal size.
Important Fit Considerations
✔ A snug fit around the cheeks and head is the correct size.
✔ Initially, the helmet may feel tight, but it will conform to your head shape over time.
✔ If you wear glasses, have permed hair, or long straight hair that needs to be tucked inside, consider choosing a size 1-2 cm larger.
✔ If you have fuller cheeks, opting for a larger size may provide a more comfortable fit.
Choosing the right helmet size is essential for both comfort and safety—measure carefully for the best riding experience!

Honestly, I was skeptical when my friend suggested the HJC RPHA 11 TEXEN MC21SF. Like many riders in Austin who swear by heavier helmets for stability, I doubted a lightweight design would hold up under pressure. However, once I slid it on and hit the road down Congress Avenue, all those worries washed away with each mile that flew beneath me. The airflow was incredible; riding through summer’s heat didn’t feel burdensome at all—my head remained pleasantly cool even after hours in the saddle! And let’s talk about visibility: this helmet is simply remarkable compared to others I’ve used before—twists and turns? No problem! Overall confidence from start to finish reshaped my view of how essential both comfort and style can coexist during rides.
