Explanation by EFX to someone who received a bad helmet:
"To put it in a simple terms, it was factory human error and a mixed up on some cleaner used during final pack out, which caused a chemical reaction between the paint and the plastic wrap that affected a small number of units.
The issue did not surfaced until after the prolonged journey in the container. And we have already resolved the issue on any new shipment going out to customers, and unfortunately, yours was one of the earlier one before the issue was discovered and action taken."
