DYNAMIC Chainsaw Trousers – Design A Class 1
Practical, comfortable chainsaw-protective trousers designed for demanding work environments, made with highly breathable, durable materials and tested in accordance with BS EN 381. They feature front cut protection additionally reinforced with waterproof, thorn-resistant fabric. The elastic construction allows unrestricted movement in seat and crotch areas, with added kidney protection and ventilation material positioned at the back of the upper thighs. Includes a large thigh pocket with internal phone compartment and carries the KWF Pro quality mark.
