A MIPS helmet is a helmet that incorporates Multi-directional Impact Protection System (MIPS) technology, which is designed to reduce rotational impact forces and protect the brain from concussion and trauma. The MIPS system consists of a low-friction layer located between the EPS and inner helmet liner that reduces rotational impact forces. This layer is designed to move slightly inside the helmet in the event of a crash, which helps to redirect forces away from the head and reduce the harmful forces that might otherwise be transferred to the riders head. MIPS technology is used in many cycling helmets, as well as equestrian helmets, construction helmets, and motorbike helmets. MIPS helmets are recognizable from the yellow liner and small yellow dot on the outside of the helmet. MIPS technology often adds extra cost to a helmet, but it is not a significant increase in price, and there are many helmets with MIPS for under £100. When choosing a helmet, it is important to consider safety standards, fit, and features like MIPS for added protection.
