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 jacket has a 3:1 rating, meaning that it has the highest level of rain protection but is 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 the Iona Lite Collection?

When functionality, added visibility and waterproof protection is required, look no further than the Iona Lite Collection. These garments are certified to the highest waterproof standard and are seam taped to ensure total protection against the rain. 

What Is the 300D Oxford Weave Material?

The jacket is made from 300D Oxford Weave Material. This 100% polyester fabric has superb abrasion and tear resistance. The outer side of the fabric has a water and stain repellent coating keeping it clean, and the polyurethane (PU) coating on the inside which makes the fabric durable and waterproof. 

What Is Texpel Splash Water Repellent Finish?

The jacket features 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?

The Portwest Rainwear collection allows for optimum outdoor performance. These garments are made from highly waterproof and breathable fabrics, ideal for protecting against harsh weather conditions. If you would like to know more about the brand try our blog on Portwest.
