Best Underlayers for FR Shirts with Moisture Wicking [2024]

Having worked with Rafeel Safety for years, I’ve helped countless clients find the perfect underlayers for their FR shirts with moisture wicking. Just a few months ago, a construction company from North America reached out with a problem. Their workers were wearing cotton undershirts under their FR shirts with moisture wicking, but they complained about feeling sweaty and uncomfortable, even though the FR shirts were supposed to wick away moisture. When we analyzed the issue, we found that cotton traps sweat instead of moving it, which cancels out the moisture wicking benefits of the FR shirts. At Rafeel Safety, we specialize in safety apparel, and our team knows that the right underlayer must complement the FR shirts with moisture wicking, not hinder them. The key principles are breathability, moisture management, and compatibility with flame resistant properties. Underlayers should be lightweight, quick drying, and made from materials that work with the FR shirts to keep workers cool and safe. We recommended our clients switch to merino wool or synthetic blend underlayers, and within weeks, they reported a huge improvement in comfort.

Merino wool underlayers are one of the best choices to pair with FR shirts with moisture wicking, and for good reason. This natural fiber is soft, breathable, and has excellent moisture management properties. Unlike regular wool, merino wool is fine and doesn’t itch, making it comfortable for all-day wear. At Rafeel Safety, we’ve tested merino wool underlayers with our FR shirts with moisture wicking extensively, and the results are impressive. The merino wool pulls sweat away from the skin and transfers it to the FR shirt, which then wicks it to the outer layer for evaporation. This combination keeps workers dry even during strenuous activities like construction or road maintenance. A client from Australia who works in outdoor electrical maintenance shared their experience: after switching to merino wool underlayers with our FR shirts with moisture wicking, their team no longer feels overheated or sweaty, even in hot weather. Our merino wool underlayers also meet strict safety standards, ensuring they don’t compromise the flame resistant properties of the FR shirts. We offer custom options, including different weights for various climates, so clients can choose the perfect underlayer for their specific needs.

Synthetic blend underlayers, such as those made from polyester and spandex, are another excellent option for pairing with FR shirts with moisture wicking. These blends are designed for high performance, offering durability, stretch, and superior moisture management. At Rafeel Safety, our synthetic blend underlayers are engineered to work seamlessly with our FR shirts with moisture wicking. The polyester fibers pull moisture away from the skin, while the spandex provides flexibility, allowing workers to move freely without restriction. We recently worked with a warehouse logistics company in Europe that needed underlayers for their team working long shifts. They chose our synthetic blend underlayers, and the feedback was outstanding. Workers noted that the combination of the underlayers and FR shirts with moisture wicking kept them dry and comfortable throughout the day, even during busy periods with lots of physical activity. Our synthetic blend underlayers also undergo rigorous testing to ensure they meet international safety standards like EN ISO 20471 and ANSI/ISEA 107. They’re easy to care for, machine washable, and resistant to wrinkles, making them a practical choice for busy workplaces.

Not all underlayer materials are suitable for pairing with FR shirts with moisture wicking. Some materials can undermine the performance and safety of the FR shirts, so it’s important to know what to avoid. Cotton is one of the worst offenders, as it absorbs moisture and holds it close to the skin, making workers feel sweaty and reducing the effectiveness of the moisture wicking FR shirts. We’ve seen cases where workers wearing cotton underlayers experienced heat exhaustion because the combination trapped heat and sweat. Another material to avoid is regular wool, which is thick, itchy, and doesn’t have good moisture management properties. According to safety expert Dr. Mark Johnson, “Using the wrong underlayer with FR shirts with moisture wicking can not only reduce comfort but also compromise safety. Materials that trap moisture can increase the risk of overheating, and in some cases, may even affect the flame resistant properties of the shirt.” At Rafeel Safety, we educate our clients on the best and worst materials to use, ensuring they make informed decisions. We also offer samples so clients can test different underlayers with our FR shirts with moisture wicking before making a bulk purchase.
