We’ve talked about breathability ratings, how your gear handles heat, and even the impact of wind and rain. But there’s another important standard to remember when choosing FR rain gear: ISO 11092. Think of it as the ultimate test for staying both dry and comfortable.


What is ISO 11092 All About?

This standard uses a “sweating guarded-hotplate test.” It may sound intense, but the idea is simple: it measures how well your rain gear releases heat and sweat vapor under controlled conditions. This test offers a more scientific view of how your gear will feel when you’re out there working hard.


Why This Matters to You

Picture this: You’re working in heavy FR rain gear. Sure, it blocks water… but what about the heat and sweat building up inside? That’s where ISO 11092 shines. It gives you insight into how comfortable your gear will be, not just how waterproof it is.

Here’s a breakdown:

  • Thermal Resistance: How well does your gear stop heat loss (good for cold weather) or release heat (better for warmer days)?
  • Water Vapor Resistance: This measures breathability more comprehensively. How easily does that sweat escape?


Gear Designed for Real-World Comfort

Understanding ISO 11092 is about finding FR rain gear that strikes the right balance for your work environment. It’s about choosing gear that protects AND lets you work hard without feeling suffocated or weighed down.


Knowledge + Protection = Workday Wins

Decoding standards might seem overwhelming, but it’s a superpower! Look for FR rain gear referencing ISO 11092 alongside other breathability standards. This gives you the best idea of how it’ll perform when you need it most.
