Selecting the Right RPP for Your Needs
For Type 2 crews and personnel who do not engage directly with flames, adhering to the NFPA 1977 minimum RPP is generally sufficient. However, Type 1 crews and those operating in wildland-urban interfaces should consider investing in fabrics with higher RPP ratings to ensure maximum safety.
Key Features of Wildland Firefighter Clothing
Breathability and Comfort
In addition to flame resistance, breathability is a vital feature of wildland firefighter clothing. Firefighters often work in extreme heat, and clothing that allows for airflow can help regulate body temperature and reduce the risk of heat-related illnesses. Look for garments with moisture-wicking properties that keep the wearer dry and comfortable.
Durability and Construction Quality
The construction quality of wildland firefighter clothing is paramount. Garments should be designed to withstand the rigors of firefighting, including abrasion from rough terrain and exposure to harsh environmental conditions. Reinforced seams, durable zippers, and high-quality stitching are essential elements to consider when evaluating clothing options.
Visibility and Reflective Elements
Visibility is another critical aspect of firefighter safety. Clothing should incorporate high-visibility colors and reflective elements to ensure that firefighters are easily seen, especially in low-light conditions. This is particularly important during nighttime operations or in areas with heavy smoke.

FAQ’s For NFPA 1977 Clothing
What is the NFPA 1977 Standard?
NFPA 1977 is the North American standard that establishes the minimum requirements for protective clothing and equipment specifically for wildland firefighting. It ensures that gear is designed to protect against the unique hazards of wildland environments, such as radiant heat and short-term flame contact, while also addressing the physical demands placed on the wearer.
Why is NFPA 1977 different from structural firefighting gear (NFPA 1971)?
Structural gear is designed for high-intensity, short-duration heat (like entering a burning building). In contrast, wildland gear (NFPA 1977) is designed for long-duration activities in outdoor environments. It is lighter and more breathable to prevent heat stroke and exhaustion, which are the primary risks for wildland crews who often hike long distances and perform heavy labor.
What is RPP (Radiant Protective Performance)?
RPP measures how long a fabric can block radiant heat before a second-degree burn would occur. Under NFPA 1977, the minimum requirement is typically a rating of 7.0 cal/cm² for lined garments or 6.0 cal/cm² for single-layer garments.
What is THL (Total Heat Loss)?
THL is a critical metric for wildland safety. it measures the fabric’s breathability and its ability to allow body heat and sweat to escape. Higher THL values mean the garment is better at cooling the wearer, reducing the risk of heat-related illnesses.
What is the difference between “Inherently Flame-Resistant” and “Treated” fabrics?
Inherently FR: The fibers themselves are fire-resistant (e.g., Nomex® or Kevlar®). This protection cannot be washed out or worn away.
Treated FR: Common fabrics like cotton are chemically treated to be fire-resistant.
Why is most wildland gear yellow?
Yellow is the industry standard because it provides the highest visibility in dark, smoky, or forested environments. This ensures that firefighters remain visible to their team and to aircraft operators during drops.
How should wildland clothing fit?
Wildland garments should have a loose fit. Tight-fitting clothing reduces the “air gap” between the fabric and the skin, which is necessary for thermal insulation and ventilation. A loose fit also provides the range of motion needed for digging fire lines and climbing steep terrain.
How should I clean my NFPA 1977 gear?
To maintain the integrity of the fabric:
Wash in warm water (approx. 40–60°C).
Use mild detergents.
Never use chlorine bleach or fabric softeners, as these can damage the FR properties and weaken the fibers.
Check for grease or oil stains, as these are flammable and must be removed before the garment is worn back on the fire line.
When should I replace my wildland gear?
Gear should be retired if it has holes, tears, or significant thinning that cannot be repaired with FR-compliant materials. Additionally, if the garment has been exposed to extreme heat and shows signs of “charring” or brittleness, it has served its purpose and must be replaced to ensure safety.
