Recommendations from our Unishore Expert
These multinorm work trousers are engineered for professionals who work in high-temperature or electrical hazard zones. The durable cotton-rich blend balances breathability with robust protection, so you stay comfortable during longer shifts without compromising on safety. The knee pockets are reinforced internally, giving you extra durability where the fabric experiences most stress. The raised back panel provides additional coverage, and the elastic waistband with adjustable leg length means you can dial in the perfect fit. For complete protection on site, pair these trousers with other items from the Tricorp Multinorm range to build a fully coordinated safety outfit.
