Is MIPS worth it in a BMX helmet?

Yes, MIPS is worth seeking out in BMX helmets if available. Oblique impacts — where the head hits a surface at an angle — are extremely common in BMX crashes, whether sliding across a skatepark floor, hitting a dirt lip, or falling onto a street obstacle. MIPS reduces the rotational forces transmitted to the brain during these impacts by 10-35%, which can reduce concussion risk. The weight penalty is minimal (20-50g), and the cost premium is typically $20-40. As MIPS becomes more common in BMX helmets, it should be a standard feature to look for.
