The Nutcase Street Helmet combines funky, out-there designs with innovative MIPS technology to ensure you remain safe while looking cool. For 2021, Nutcase has redesigned the Street model to be more secure and comfortable with an all-new retention system. While the addition of MIPS technology ensures your head is protected from rotational forces in the event of a fall. As part of their latest design ethos, Nutcase has increased the reflectivity of the Street Helmets, thus improving visibility on-road. Although, the charismatic designs are hard to miss!

You'd expect with the additional protection, and reflectivity that the Nutcase Street Helmet would be hot in summer, however, this couldn't be further from the truth! The Nutcase Street Helmet now features 10 air vents to increase airflow to your scalp at all speeds.

Once again, Nutcase has proved the world wrong. You can be outlandishly stylish, yet safe and practical thanks to the Nutcase Street Helmet!
