Thermal Liner | TenCate Protective Fabrics
Defender® M SL2 is a structural firefighting thermal liner engineered to balance thermal protection, lightweight comfort, flexibility, and moisture management. Its facecloth incorporates COOLDERM™ Technology to help move moisture away from the body, while a two-layer spun-lace batting system provides thermal insulation without unnecessary bulk.

As the innermost layer of the protective composite, Defender® M SL2 is designed to support both thermal protection and wearer comfort during structural firefighting operations.
A two-layer spun-lace batting construction helps balance thermal insulation with lightweight comfort and flexibility.
Integrated moisture-management technology helps move moisture through the facecloth to support evaporation, breathability, and wearer comfort.
The flexible facecloth and batting system is designed to reduce bulk and support freedom of movement inside the complete turnout ensemble.
