Safety Notice and Use Limitations

IMPORTANT: This garment has been designed to improve the wearer's visual detection in risk areas. It is NOT a garment for protection against thermal risks (flame retardant), it is not anti-static, and it does not offer protection against chemical or mechanical risks. It should not be used as a substitute for specialized protective equipment in areas with a risk of contact with flames, sparks, or explosive atmospheres. Verify that the garment is not obstructed by other accessories to ensure its effectiveness.

Maintenance and Care Instructions

• Washing: Machine wash with neutral detergent. DO NOT use fabric softeners, as these products clog the pores of the Cotton Comfort™ fabric and degrade the effectiveness of the reflective tapes.
• Drying: Air dry or tumble dry at a low temperature. Avoid industrial drying at high temperatures to prevent fiber degradation.
• Ironing: Iron at a medium temperature. DO NOT iron directly over the reflective tapes; direct heat destroys the retroreflection capability required to comply with EN ISO 20471.
• Inspection: Before each use, check the condition of the reflective tapes. If they show cracks, wear, or loss of brightness, the garment no longer complies with safety regulations and must be replaced immediately.
