Portwest DX4 Evolution Ripstop Winter Jacket - Black
Portwest DX4 Evolution Ripstop Winter Jacket - Navy
EN343 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 pictogram to the left indicates that protection against rain is offered.
The standard provides for two performance parameters of which there are 4 levels with Class 4 offering the highest level of protection.
EN342 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:
(Example to the left refers to the Portwest Hi-Vis Bomber Jacket (S463) test results)
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.
For example (see chart to the left):
A person wearing the Portwest Hi-Vis Bomber Jacket (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.
Constructed using hollow fibre technology, Insulatex™ provides a lighter and warmer thermal lining. The unique fabric technology locks in the body's warmth to create a thermal barrier whilst the high-performance fine knit offers superior lightweight comfort to the wearer without adding bulk.
Made with 300 Denier 100% polyester yarn, this is a tough fabric for tough conditions. 300D fabric has superb abrasion and tear resistance. The double polyurethane (PU) coating on the inside makes the fabric durable and waterproof, and the outer has a water and stain repellent coating which helps keep the garment clean.
