Concussive absorbing material was a physical substance that could be integrated into garments. Certain items in Queen Padmé Amidala's collection of clothing, circa 32 BBY, incorporated this material; one of the Naboo Royal Handmaidens fashioned protective headbands from it amidst the Invasion of Naboo.
The 2020 book Queen's Peril, penned by E. K. Johnston, features concussive absorbing material.
