Nutcase Street Helmet Medium MIPS (56-60 cm)


Nutcase Street Helmets are suitable for all street activities: bike, skate, roller and scoot. They come in 3 sizes, small, medium and large. Nutcase helmets have been designed with the prime focus being the safety of the rider. If the Nutcase Street helmets are too big, consider the Little Nutty and Baby Nutty range. These easy-to-use helmets will make it even simpler for you and your family to enjoy riding.

Nutcase were the first helmet brand to incorporate the Multi Impact Protection System (MIPS) into their ranges in 2018. Unlike standard helmets that combat linear forces, MIPS helmets are designed to also withstand rotational forces that result from certain impacts. MIPS use a slip-plane system that  mimics the brains own protection system, moving inside the helmet. The slip-plane rotates within the helmet with the aim of slowing and/or reducing the energy transferred to or from the head. Reduce your carbon emissions, spend time outside, exercise, and look stylish with a Nutcase helmet!
