MIPS was founded on the goal of better protecting the brain in the event of a crash. As a result of their research, that seems to keep coming back to the idea of rotational motion which is what’s responsible for straining your brain. That’s why the original MIPS (Multi-directional Impact Protection System) liner was designed to reduce the rotational impact during a crash while the helmet does its job to reduce the linear impact. But as helmet designs evolve, MIPS has been in search of new options to fit a wider variety of helmets.
The new A1 system, or ‘the Pocket’, is essentially a miniature MIPS liner contained in a velcro disc. Created with a series of hard plates layered between low friction fabric and attached with velcro to the helmet an the pad, the A1 allows for the same 10-15mm of movement in the first 2-3 milliseconds that is critical to the protection of the MIPS system. This should allow the same level of protection to be built into helmets with better ventilation since a large liner is no longer needed.
Available in either rectangular or circular designs, the Pockets will be chosen based on the helmet design.
