Pockets for impact protectors crossing over two zones shall meet the higher zone requirements, if applicable For garments with externally attached impact protectors (not in pockets):
— exposed portions of the impact protectors and their attachment systems shall meet all appropriate zone requirements (zones determined according to EN 17092-1:2020, 5.2). Attached protectors shall not be released from the garment during testing.
