Ever felt like you’re wearing a plastic bag instead of rain gear? Struggling to concentrate because your gear is turning you into a walking sauna? Low breathability might be the culprit. Those confusing numbers on FR rain gear labels aren’t there to baffle you – they give you clues about how comfortable you’ll be out on the job site.

Breathability: Your Invisible Comfort Factor

Think of breathability like this: it’s your rain gear’s ability to let sweat vapor escape while keeping rain out. Picture breathing through a plastic bag versus a thin mesh – that’s the difference between feeling trapped and clammy, versus staying drier on the inside. Why does it matter? Overheating in FR rain gear isn’t just uncomfortable. It messes with your focus, drains your energy, and in serious cases, leaves you vulnerable to heat-related health issues.

Decoding the Jargon

You’ll probably see terms like MVTR and RET when looking at FR rain gear. These are breathability ratings.

  • MVTR (Moisture Vapor Transmission Rate): The higher the number, the more sweat can escape over a certain period of time. Think of it as breathability on a scale – a higher MVTR means you’ll feel less clammy.
  • RET: This measures how much resistance the fabric creates to sweat evaporating. A lower RET number means the fabric lets sweat escape more easily.

Ratings are helpful, but they’re not the whole story. Imagine two jackets with the same MVTR rating, but one is made with stiff, heavy fabric and the other with a lightweight, flexible one. Guess which one will FEEL more comfortable, even on paper?

Look Beyond the Numbers

The type of FR material and the way your gear fits also play a huge role in comfort. Gear that’s too tight traps heat and moisture, canceling out even a decent breathability rating. You want rain gear that lets you move freely without feeling like you’re wearing a bulky suit of armor.

Knowledge = Staying Comfortable (and Safe)

Understanding breathability ratings is about more than buying the right gear; it’s about making those long, demanding jobs easier. Next time you’re choosing FR rain gear, consider breathability ratings alongside protection. It’s an investment in your comfort, focus, and the ability to do your best work, rain or shine. At NASCO Industries, we’ve been making FR rainwear for more than 40 years, and we have the gear you need to stay dry and comfortable.
