How do we measure the level of water resistance of this MH500 children’s jacket?
The resistance of a fabric is measured by the height of a water column in mm that can be supported by the fabric (test based on the JIS 1092 standard)The higher the water pressure, the more waterproof the fabric.This wtp jacket can withstand the pressure that is exerted by 5,000 mm of water (roughly equivalent to a 1h-long downpour)
The MH500 wtp raincoat was placed for 1h under a shower discharging 60L of water/sqm/h.This test reproduces the average conditions of a rain shower in the mountains.
How breathable is the MH500 waterproof jacket?
Component breathability is measured by its thermal evaporative resistance (RET).
This is its capacity to let water vapour generated by the body during physical activity escape and therefore avoid water accumulating on the skin.
The lower the RET, the more breathable the fabric.
RET ≤ 6: very breathable fabric
RET ≤ 12: breathable fabric
RET ≤ 20: little or no breathability
How are the different components of the MH500 children's raincoat tested for their level of strength?
Resistance to wear and abrasion test: for example, we check that our fleeces do not pill using tests conducted in laboratories. Colour retention test: the colour fastness is verified to ensure that the colours do not bleed when coming into contact with saliva. Ageing test: repeated washing should not affect the fabric's properties, behaviour, thickness or appearance.
How to look after the MH500 children’s waterproof raincoat
1/ Machine wash (30 to 40°C): fasten hook and loop tabs and zips, use gentle detergent. Jackets and trousers turned inside out. Loosen straps and elastics.
2/ Avoid folding the garment too much in the washing machine: this can damage it.
3/ Do not mix clothing styles and colours.
4/Do not use bleach or fabric softener.
5/ Choose a full rinse and gentle spin cycle.
6/ Either line dry or tumble dry (low temperature + fastest cycle).
