Where these two actually differ
- We flag Heavy metals in unspecified hardware, Thermal degradation of polyester and nylon and Microplastic shedding from synthetic fabric on the Kata and not on the Kata.
- We flag Durable water repellent (DWR) coating composition and Coating degradation and particle release on the Kata and not on the Kata.
- The Kata is Nylon and polyester fabric with unspecified hardware where the Kata is Ballistic nylon with unspecified water-resistant treatment, which is most of the difference in these two grades.
- The gap is 45 points, wide enough that this is not a close call, and the Kata is the one to buy.
