Professional FAQ – Work Pants Technical Glossary
- Q1. What is “Reinforced Knee” in work pants?
- A: Reinforced knees refer to an extra layer of ultra-durable textile (often 1000D Oxford or Cordura®) sewn over the knee area, protecting from abrasion and extending the product lifetime according to ISO 12947-2 standards.
- Q2. Why is “RET” (Breathability) testing critical?
- A: RET (Resistance to Evaporative Heat Transfer) [ISO 11092] indicates how effectively the fabric wicks sweat, maintaining body comfort in hot or high-intensity environments.
- Q3. How does the “Adjustable Waist” improve jobsite safety?
- A: An adjustable waist ensures a secure, non-restrictive fit, preventing snagging and slippage, which can be a safety hazard during climbing, crawling, or lifting.
- Q4. What are “Martindale Abrasion Cycles”?
- A: This is a laboratory test quantifying the number of rub cycles a fabric can withstand before breaking down, with >50,000 considered heavy-duty by industry standards (ISO 12947).
- Q5. Are the pants compliant with “ISO 20471” for high-visibility?
- A: Yes, when ordered with hi-vis trims, they comply with ISO 20471 Class 2 for professional visibility and safety in low-light environments.
- Q6. What is the difference between “Ripstop” and regular fabric?
- A: Ripstop fabric has a reinforced, grid-like structure that prevents small rips from spreading, significantly improving durability and resistance to tears.
- Q7. What does OEKO-TEX® Standard 100 mean for work pants?
- This certification ensures all textile components are free from harmful substances, supporting both wearer safety and environmental sustainability.
