Recommendations from our Unishore Expert

These multinorm work pants deliver exactly what you need if you're working with thermal hazards, electrical risks, or chemical splashes. The cotton-rich composition provides breathability for longer comfort during full shifts, whilst the flame retardant technology protects against radiant heat, contact heat, and even molten metal splashes. The elastic waist makes a genuine difference in comfort when you're bending, climbing, or moving constantly throughout the day. The reflective bands aren't just about visibility - they're built into the design with industrial-grade thread that withstands repeated washing. If knee protection is part of your routine, you'll appreciate the two pocket positions that let you wear protection at shin or knee height depending on your preference. These work trousers respect your budget without cutting corners on safety.
