Our backpacks are rated Level IIIA, which means they will protect against handguns firing 9mm to .44 magnum.

For more information on NIJ Protection Levels and what they mean, we recommend this helpful flyer created by the JTIC (Justice Technology Information Center) and shared by the OJP (U.S. Department of Justice: Office of Justice): https://www.ojp.gov/pdffiles1/nij/nlectc/250144.pdf
