In short, the answer is no. FR/AR engineering is durable enough to withstand laundry and even industrial laundry. We now offer a wide variety of different FR/AR fabrics, all with lifetime FR/AR properties. That’s why Bulwark can guarantee the flame-resistant properties of all our FR/AR garments are good for the lifetime of that garment. The lifetime of the garment does vary, based largely on how each person wears it. It depends on the duties of your job and how rough your day-to-day work is on your clothing in general. But, because our FR/AR properties are good for the life of the garment, you can feel safe wearing your Bulwark FR/AR clothing as long as the garment can be worn in a useful condition.
