Is MIPS worth the extra cost in an enduro helmet?

Yes. The types of crashes common in enduro riding—oblique impacts with rocks, roots, and hardpack—are precisely the scenarios where rotational protection systems provide the most benefit. MIPS reduces rotational acceleration by 10-35% in oblique impacts, which is linked to reduced concussion risk. Given that enduro helmets already represent a premium purchase for aggressive riding, the additional $20-40 for MIPS is a worthwhile investment in brain protection. MIPS Spherical and WaveCel offer enhanced protection at higher price points.
