Description
The Portwest S451 waterproof rain trousers offer professionals and outdoor enthusiasts reliable protection against extreme weather conditions. These over-trousers are designed to be worn over regular workwear and are guaranteed to keep the wearer dry while working in pouring rain. Thanks to their flexible properties, this model is ideally suited for prolonged use in demanding outdoor environments where freedom of movement and a high level of moisture protection are essential.
For which tasks are these waterproof rain trousers from Portwest most suitable?
These waterproof rain trousers are ideally suited for outdoor work in the agricultural sector, construction, logistics, and for recreational outdoor sports. Thanks to the welded seams and water-repellent coating, the wearer stays dry during heavy rainfall.
The supple stretch fabric ensures that you can bend and move without hindrance. The easy-to-wipe finish also makes the trousers highly practical for muddy and dirty work environments, as dirt does not adhere to the fabric and is easily removed.
What does the EN 343 Class 4:1 X rating mean for these Sealtex Classic trousers?
The EN 343 Class 4:1 X rating indicates that these Sealtex Classic trousers meet the highest class for waterproofing. The class 4 certification guarantees a water column of at least 5,000 millimetres, which provides excellent protection against penetrating rainwater.
The class 1 rating for breathability means the trousers are primarily designed as a barrier against heavy precipitation. This makes the model perfect as over-trousers that can be pulled on quickly and easily over your own trousers during sudden downpours.
The fully elasticated waistband ensures a comfortable fit, while the stud-adjustable hems at the bottom of the trouser legs ensure a snug fit over your work boots.
