IFR coveralls are designed to be inherently flame-resistant, meaning their flame-resistant properties are built into the fabric itself and do not wash out or diminish over time. FR coveralls, on the other hand, are typically treated with a flame-resistant chemical coating that can wear off with washing and use, making them less durable in maintaining flame resistance compared to IFR coveralls.
