BP4 L1 Back Protector

Home Partner Support Products > BP4 L1 Back Protector

The D3O® BP4 L1 Protector offers highly breathable, durable back protection that exceeds CE Level 1 certification.

Exceptionally soft and flexible, the BP4 is the most breathable back protector on the market, delivering 34% more breathability than the next best competitor.

The fabric loophole positioned at the top of the part allows the more accurate positioning of the protector within the jacket.

The tapered outer edges allow for a closer, more comfortable fit to the wearer, and also create less visual read through once inside of the garment.
