Recommendations from our Unishore Expert

These stretch work trousers are built for professionals who need reliable protection without compromising on movement. The blend of materials creates a robust yet flexible garment that responds to your working position, whether you're bending, climbing, or reaching. The articulated knee design works brilliantly with the adjustable interior knee padding, giving you control over where support sits. The wide rear belt loop keeps everything secure, and with the crotch gusset in place, you've got genuine freedom to work without restriction. The extended hem option is a genuine asset if your inseam falls between standard sizes, plus those handy holster pockets and thigh storage mean your tools and essentials stay organised throughout your shift.
