Breathability
To determine whether a fabric is breathable, we measure its evaporative resistance (test based on standard ISO 11092).
The lower its resistance, the more the fabric will let water vapour produced by the body escape, and therefore the more breathable it is.
For example: RET < 9 = extremely breathable material
The RET of our Ultralight showerproof jacket is 6.
Care tips
Hand wash.Turn the garment inside out. Use minimal laundry detergent. Do not add softener. Line dry in a warm, ventilated area. Do not tumble dry.Do not dry clean. Do not bleach. Do not place on a heater to dry.
Product tests
Our team of product designers is based at the B'Twin Village in Lille (France). All year round, we conceive and develop new products that are easy to use, look great, and have the technical features needed for your cycling experiences.
They are then mercilessly put to the test by users in the field, as we are convinced that only by subjecting our products to real world conditions, such as the ones you will experience on your bike, can we continuously improve them.
Instructions.Repair patch
1. Carefully clean the area with a dry cloth. Avoid touching the adhesive part.
2. Put the patch inside the jacket by letting it extend 1 cm around the hole (recut if necessary). 3. Put firm pressure on the surface in order to remove the air and ensure good adhesion.
Washing temperature: 30 °C, 10 wash cycles max. A tutorial video is available to apply the patch on the arm area.
Waterproofness
Waterproofing is a fabric's capacity to prevent penetration of rain water. The resistance of a fabric to water pressure is expressed in mm of a water jet (test based on standard ISO 811). The higher the pressure, the more waterproof the fabric.
Material with a waterproof rating of 2000 mm resists the pressure exerted by 2000 mm of water (which roughly corresponds to a 2-hour rain shower).Our Ultralight jacket is waterproof up to 2000 mm.
