The micro-adjustable BOA® Fit System provides fast, micro-adjustability for a customized and fine-tuned fit.
The MIPS® safety system features a low-friction layer inside the helmet, generally between the padding and the eps foam protective layer, that allows a multi-directional movement of 10 -15mm on certain angled impacts, intended to help reduce rotational force to the head. Oakley helmets feature either the MIPS Series B or MIPS Air.
