Defender® M SL2

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.

Manufactured by TenCate Protective Fabrics
