The lifespan of firefighting garments is affected by smoke gases, particles, heat, wear, and washing. The greatest impact on the lifespan of CPP Garments' undergarment comes from smoke gases and particles that are absorbed by the activated carbon, gradually saturating it.
Washing has less impact on the garment's lifespan, and its function remains essentially unchanged even after many washes, if done according to instructions.
According to extensive studies conducted between 2019-2021, including those by Chalmers University, the protection provided by the undergarment is as follows compared to current standard equipment.

• New turnout gear and new undergarment: 99.99% vs. 90% i.e., approximately 200 times higher protection.
• After 24 smoke dives of 25 minutes each (10 hours) including washes: 99.3% vs. 85% i.e., approximately 20 times higher protection.
