Protect your head from impacts! Impact-reducing head cap
Patented Technology: Defentex ™
It is made up of five layers, which overturns the conventional wisdom of head caps.

Impact reduction is up to 75% compared to other companies
It was designed to reduce impact and was created through repeated crash tests and analysis. Although it looks like a head cap, its structure is very different, which is why it has the effect of reducing impact.
Continued performance even after 3 years of impact
In durability tests, the product is subjected to repeated impacts (1,920 collisions) to simulate the number of impacts that an athlete would receive over a three-year period. Even after this number of impacts, the product continues to maintain its high impact reduction effect.
