The following designs enables the full 10-15mm of rotational movement in the crucial 2-3 milliseconds following angled head impact, redirecting damaging rotational motion. The choice of system comes down to how the helmet is designed and engineered.
The MIPS:A1 solution is a series of plates anchored between fabric layers and housed beneath a helmet’s comfort pads. Thanks to each plate’s low-friction plastic construction and stretch fabric, the MIPS:A1 is able to protect against damaging rotational motion with a detailed level of integration in the helmet’s construction.
The MIPS:C2 solution separates the shell and the liner with a thin plastic Low Friction Layer (LFL). This LFL, attached with 3-4 rubber elastomers combined with a low friction ink, allows the helmet to slide relative to the head without affecting comfort or ventilation. The majority of today's helmets equipped with MIPS feature the MIPS:C2 solution.

The MIPS:E2 solution is a soft, cap-like insert that acts as a full-headed low-friction layer for full-face cycling, motocross, and street sport helmets. The MIPS:E2 liner is made up of two multi-directional, stretch fabric layers sewn together around a thin, plastic foil. When inserted between the comfort padding of the helmet and the outer EPS shell, the Liner provides broad coverage from rotational impacts without sacrificing comfort or sweat absorption.
