With the Projob 5531 work trousers, you stay comfortable and fully prepared on the jobsite or during renovation projects. The hard-wearing blend of polyester and cotton retains its shape and color through demanding daily tasks. Practical holster pockets, a leg pocket, and a folding rule pocket with a knife button keep your essential hand tools and fasteners readily accessible. If you spend time kneeling during carpentry, plumbing, or flooring installations, the internal kneepad compartments adjust across two height levels for reliable joint protection. Additionally, the hem on size C48 can easily be extended by 5 cm for a tailored fit.
