What Should Firefighters Wear Under Brush Gear?

Wildland firefighters needn’t worry about being fashionable. Brush gear is less about looking good and more about protection and the ability to move freely while battling a blaze. Fire-resistant brush gear usually consists of a few basic pieces such as brush gear shirts, pants, jackets, helmets, and the like. Those items are deeply important, of course, and can save their lives. But what should firefighters wear under their brush gear? Base layers make all the difference in keeping firefighters cool and able to perform their duties.

Material Issues

The first thing to keep in mind is to choose underlayers that are moisture-wicking. This type of material prevents sweat from building up on firefighters’ skin, which may cause severe chafing and discomfort, and protects the firefighter from heat stroke and other heat-related issues. Base layers should also provide extra protection against the effects of flames and heat. Here are a few materials to consider and how they help:

  • Wool is a traditional material that offers some natural protection against heat and fire while also providing insulation to keep the firefighter cool and naturally wicking away moisture.
  • Cotton is another natural fiber that allows skin to breathe easily. It’s not flame resistant on its own, but manufacturers can treat it to offer more flame resistance. Such treatment might interfere with cotton’s natural breathability, however, and may make the fabric less comfortable for the firefighter to wear.
  • Technology steps up with flame-resistant yet breathable Nomex and Kevlar synthetic fabrics. Both also offer excellent wicking properties.

Comfort and Fit

Once you pick a material for your undergarments, consider how your base layers feel and the way they react while performing your duties. Base layers should fit snugly against the body for improved moisture wicking and to avoid snags. Also, make sure you can move freely and comfortably. Dress in base layers and see if you can move and operate equipment without discomfort or hindrance.

In-Between Layers

You might still deal with frostbite, hypothermia, and other chilly conditions as the temperature drops, even as the flames rise. A mid-layer of clothing is wise, though once again, be sure they don’t interfere with the top layers, movement, and more while wicking away moisture and fighting flames. Fleece is your best choice of material. It’s often flame-resistant and provides extra warmth without adding extra weight to a firefighter’s body.
