What Is the EN 343 Standard?

The EN 343 Standard outlines the garment's level of protection against wet weather. The garments are rated on their response to precipitation, fog and humidity, and then on their breathability under those conditions. The trousers have a 3:1 rating, meaning that they have the highest level of rain protection but are not classified as breathable under EN 343. 

Level Water Resistance Breathability
Level 1 Minimum level of rain protection Not classified as breathable under EN 343
Level 2 Intermediate level of rain protection Intermediate level of breathability
Level 3 Highest level of rain protection Highest level of breathability

What Is Sealtex Classic? 

Sealtex is a high-technology, PU-coated fabric, on a flexible, resistant polyester, which consistently achieves top scores on hydrolysis and hydrostatic testing. Sealtex garments like these trousers are guaranteed to keep the wearer dry in adverse conditions, with welded seams to ensure wind and rain are locked out. The durable stretchy fabric can be easily wiped clean, allowing all Sealtex garments to look good and last for longer. 

What Is Texpel Splash Water Repellent Finish?

The trousers feature a Texpel Splash water-repellent finish. This means that water beads away from the fabric surface, all while allowing for maximum breathability. Texpel also repels dirt, prevents stains and enhances the removal of any stains that do occur. 

What Is Portwest's Select Rainwear Range?
