Helly Hansen Fyre Construction High Visibility Work Pants Class 1 77450

If you work in construction or industrial settings where flame hazards and visibility are critical concerns, these Helly Hansen Fyre Construction multinorm work pants deliver serious protection without compromising on comfort. Built with inherently flame-retardant material, these long work trousers keep you safe from arc flash incidents whilst ensuring you're highly visible to colleagues and equipment operators. The 2-way stretch fabric moves with you, whilst the thoughtfully positioned knee pockets with internal access let you adjust protective padding to suit your comfort needs. With practical holster pockets, thigh pockets with secure closures, and an extendable hem for a personalised fit, these high visibility work trousers balance functionality with wearability across demanding job sites.

Key Features

  • Inherently flame-retardant material protects against arc flash hazards
  • 2-way stretch fabric allows unrestricted movement throughout your shift
  • Adjustable knee pockets with 5 cm padding for customisable comfort
  • Multiple practical pockets including holster and thigh pockets with closures
  • Hem extends by 5 cm for personalised trouser length

Recommendations from our Unishore Expert

These multinorm work pants are engineered for roles where multiple hazards converge on a single job. The inherent flame protection built into the fabric means you're safeguarded whether you're working near welding operations or electrical equipment. The generous stretch sections make a real difference when you're climbing, bending, or working from height, whilst the reinforced knee area is designed to accommodate protective padding exactly where you need it. The wide rear belt loop provides genuine stability when carrying tools, and the ID card holder keeps your credentials accessible. For anyone serious about balancing protection with practicality, these construction work trousers represent solid value.
