We measure the resistance of a fabric to water pressure in mm of water column (based on the ISO 811 standard). The higher the water pressure withstood by the fabric, the more waterproof it is.
Here are the waterproofing ratings:
Component resistant to water pressure of 5,000 mm before and after ageing (5 washes). This equates to 5 000 Schmerber - average pressure exerted by the water during rain.
The anorak's waterproofness was tested in a rain shower with 60 litres of water / m² / hour for 2 hours.
- High collar
- Injection-moulded plastic to avoid salt oxidation
- Water-repellent components (water runs off the fabric)
- 100% taped seams
- Central opening features a flap with a drainage channel for optimal waterproofing
The hood does not pack down into the collar, it is attached.
Completely depth and height-adjustable hood.
Visor with a headband to provide a good level of protection and a better hold.
The high neck effectively protects the neck.
2 zip pockets on the front of the jacket to put your hands or some items
1 inside pocket on the right side of the chest with a rip-tab closing
NOTE: the pockets are NOT WATERPROOF
Front zip closure
A zip on the entire jacket length with an interior flap protects against the wind and water.
Soft fabric flap on the top of the collar to protect the chin.
To find out whether a fabric is breathable, we test its evaporate resistance or RET (ISO 11092 standard). The lower the fabric's resistance, the more moisture is evaporated, and therefore the higher the fabric's breathability.
We consider that if:
RET < 9 = very breathable fabric
9 < RET < 12 = breathable fabric.
The values for the Trek 500 jacket’s breathability are as follows:
> More resistant fabric: RET < 12 (or 3621 g/m²/24 h, JIS1099A standard)
> Lightest fabric: RET < 8 (or 2972 g/m² /2
Water-repellent properties information
A fabric is water-repellent when water slides off the surface of the fabric, without seeping in.
Your jacket does not become waterlogged and remains lightweight and breathable. The water-repellent properties are achieved with a treatment applied to the external side of the fabric, but in practice these properties can be altered.
The water-repellent properties can be reactivated by putting the anorak in a dryer for 10 minutes at the lowest temperature.
How to wash your jacket?
To maintain the water repellent properties, infrequent washing is recommended.
Close all zips and flaps, empty all pockets and then turn the garment inside out to wash it. You can wash it on a synthetic cycle at 30°C or 40°C with your usual detergent. Do not use fabric conditioner, which could damage the existing performance of the garment, or bleach. Very important: choose a full-rinse cycle or extra rinse.
How to reactivate the anorak's water repellency
Drying is a crucial phase in reactivating the water repellent treatment.
We recommend that you lay your anorak flat on a clothes rack and leave it out to dry in the open. Caution: never dry your anorak directly on a radiator.
Then place it in the tumble dryer on a short synthetics cycle, i.e. 10 to 15 minutes, before turning it back the right way round. Caution: do not over-dry the garment.
