In the market for a flight suit? Our flame-resistant flight suits, worn by all U.S. flight crews, have all the functional features you need to take the skies with confidence. Propper currently offers flight suits in 3 different fabrics, but for the purposes of this article we’re going to focus on Aramid. What makes Aramid such an appealing option is it basically meets all the same criteria as our original Nomex flight suit but at a more reasonable price point.

What is Aramid?

Aramid is a class of synthetic fiber used extensively in military and aerospace applications. Its chemical ring structure forms a chain that aligns with the length of Aramid fibers, creating a bond that makes the material extremely durable. In fact, an Aramid cord can have a tensile strength-to-weight ratio up to five times stronger than steel. In addition to being the material found inside most modern body armor, some other practical applications of woven para-aramid include reinforcing racing tires and cargo ship hulls.

Aramid also has excellent electrical and heat resistance, which makes it a natural fit for a wide range of PPE (personal protective equipment). Specialized meta-aramid fabrics are so flame resistant that they will not melt or ignite under normal oxygen conditions.

Military or Civilian?

Every flight suit Propper makes is built to military specification YACL-WP PD 99-01 R. From a design and features perspective, they are identical in every way save for the fabric itself. However, if you need your flight suit to be NIR compliant, the Aramid flight suit will not be a suitable option.

An NIR-compliant flight suit is essential for flying combat missions because it mimics the same radiation levels as the ambient environment, making them harder to detect using near-infared imaging (NIR) technology. If any of your flight hours are going to be spent in hostile territory, you’ll probably need to opt for the Nomex flight suit, specifically the Freedom Green and Air Force Tan colors.
