Portwest FR Stretch Work Trousers FR404

When you need long work trousers that deliver both safety and comfort on the job, the Portwest FR Stretch Work Trousers FR404 stand out as a solid choice. Designed for professionals who work around electrical hazards, these flame-resistant work pants combine protective performance with practical everyday wearability. The soft Bizflame 88/12 stretch fabric has been garment washed to feel genuinely comfortable against your skin, whilst the slim-fit cut keeps things neat without restricting your movement. You're getting proper protection against thermal hazards from electrical arcs, radiation, convection and contact heat, all backed by strict international safety standards. With four storage pockets for your essentials and an extendable hem that adjusts up to 5cm, these durable work trousers adapt to your needs rather than the other way around.

Key Features

  • Protects against electrical arc thermal hazards
  • Soft stretch fabric with garment wash finish
  • Extendable hem length up to 5cm
  • Four practical storage pockets
  • Slim-fit design with flexi-fit movement

Recommendations from our Unishore Expert

These FR work trousers are built for anyone who needs reliable protection without compromise. The stretch composition delivers genuine comfort during a full shift, and you won't feel restricted when you're moving around the job site. The extendable hem is particularly useful if you're between sizes or prefer a specific break on your boot, saving you the hassle of alterations. The four pockets give you proper space for tools and personal items, whilst the two rear patch pockets sit securely without adding bulk. Choose these trousers when you want protective work pants that actually feel good to wear.
