The Portwest IONA S482 cleverly designed to keep the wearer visible, safe and dry in foul weather conditions
The S482 is extremely practical and waterproof. Reflective tape offers superb protection in low light conditions whilst the padding traps the heat to make you warm and comfortable.

Documentation
EN 343 is the European standard that applies to garments worn in adverse weather conditions
This standard specifies requirements and test methods applicable to the materials and seams of protective clothing against the influence of precipitation (e.g. rain, snowflakes), fog and ground humidity.
The standard provides for two performance parameters of which there are 4 levels with Class 4 offering the highest level of protection.
- X Water Penetration Resistance (Waterproofness) 4 Levels
- Y Water Vapour Resistance (Breathability) 4 Levels
- R Readymade Garment; Rain Tower Test (optional)
R may be replaced by an X if the test has not been carried out or is not suitable.
EN 342 - is the European standard that applies to garments worn in cold environments
This standard specifies requirements and test methods for the performance of clothing ensembles (i.e two-piece suits/coveralls) for protection against the effects of cold environments equal to or below -5°C.
There are three main parameters:
- A Thermal insulation (this is tested using a full-size moving mannequin & measures the amount of energy required to maintain warmth)
- B Air Permeability (This is a measure of how windproof the garment is), AP, Class 1-3 (where 3 is best)
- C Water penetration (waterproofness) Class 1-2 (where 2 is best); optional test
Wear Time
The manikin test measures the amount of energy required to maintain warmth. This result is expressed in square metres Kelvin per Watt (m2K/W) this result can be used to estimate the maximum wear time based on the activity level of the wearer, the temperature of the environment and insulation value of the garment.

| Garment Insulation Icler (m2K/W) | Wearer Activity (Light) | Wearer Activity (Medium) |
| Air Velocity (m/s) | Air Velocity (m/s) |
| 0.4 | 3 | 0.4 | 3 |
| 8hr | 1hr | 8hr | 1hr | 8h | 1hr | 8hr | 1hr |
| 0.336 | -2 | -18 | 6 | -8 | -18 | -36 | -7 | -22 |
A person wearing S463 performing light activity can withstand -2°C for 8hrs and -18°C for 1hr. A person performing Medium activity can withstand -18°C for 8hrs and -36°C for 1hr.
