Most of the highly rated ski helmets on the market in 2023 are built with a rotation force mitigation system. To date, MIPS is the most common and well-known, and not many competing technologies exist.
Smith integrates Koroyd impact protection in many ski and snowboard helmets and even couples the technology with MIPS in certain models. Scott integrates a shock-absorbing material called D3O, which is likewise added alongside MIPS. Bontrager features WaveCel in bike helmets but does not produce snow sports helmets.
Formerly, POC designed its own solution, known as SPIN, which the brand began to phase out and replace with MIPS in 2019. We recommend purchasing a helmet with MIPS or a comparable system.
