Three Trousers in One – The Most Versatile Work Trousers You'll Own

Portwest's BX321 Ultimate Modular 3-in-1 Trouser adapts to whatever your workday throws at you. Full-length trousers in the morning, shorts when the temperature rises, or EN ISO 20471 Class 1 hi-vis trousers when you need roadside visibility. One pair of trousers, three configurations, no compromises.

Key Features:

• Innovative 3-in-1 Design: Converts from full-length work trousers to shorts, or deploy the visibility panels for EN ISO 20471 Class 1 hi-vis compliance. When you're wearing them as shorts, the legs fold up and store securely – no awkward bunching or lost parts.
  
• Titanmill Ultra Stretch Fabric: Constructed from 92% Nylon and 8% Elastane (230g) with 4-way stretch. Squat, climb, kneel – these trousers move with you, not against you. The CorePro contrast fabric adds durability at high-wear zones.
  
• 15 Pockets Total: Magnetic flap pockets stay out of your way during work. Large built-in side pockets hold spray cans or bulky tools. Front-leg cargo pocket for quick access. Mesh mobile phone pocket keeps your device secure. Knee pad pockets with side openings accept S156 knee pads (sold separately) for EN 14404:2004+A1:2010 Type 2 Level 0 compliance.
  
• Clip-On Pocket System: Compatible with Portwest's B920, B921, and B922 accessory pockets. Attach them to the front or back depending on your trade. Electricians, plumbers, and carpenters can customise their storage setup in seconds.
  
• Slim-Fit Comfort: Integrated waistband and adjustable hip belt create a tailored fit that doesn't sag or bunch. The slim-fit design looks professional without restricting movement.
