Breathability is an important functionality of a large part of our jackets. Breathability is a technique that allows moisture to escape from the inside to the outside while preventing water from entering from the outside. Microscopic openings have been made in the TPU lamination of our fabrics. These are smaller than water droplets, so that water does not penetrate the fabric but vapor can escape. Breathability is tested with the Moisture Vapor Transmission Rate (MVTR). This test measures the speed at which moisture passes through fabric. The MVTR is measured in grams per square meter of fabric per 24 hours (g/m2/24h). How you can imagine this is that a fabric with a breathability of 3000g/m2/24h, can allow up to 3000 grams of moisture vapor per m2 of fabric to pass through in a period of 24 hours. The higher the MVTR value, the better the fabric breathes.
Breathability - Effort
>3000 g/m2/24h - Light exertion, like normal cycling
>5000 g/m2/24h - Strenuous exercise, such as hard cycling
It is important to keep in mind that breathability measurements are affected by factors such as the construction of the fabric, its thickness, and any coatings or treatments applied to the fabric. Additionally, the individual's perception of breathability can vary depending on your activity, environmental factors, and personal preferences.
