Breathability is an important functionality of many of our jackets. Breathability, or breathability, is a technique that allows moisture to escape from inside to outside while ensuring that water from outside does not enter. Microscopic openings are made in the TPU lamination of our fabrics. These are smaller than water droplets, preventing water from penetrating the fabric but allowing vapor to escape. Breathability is tested using the Moisture Vapor Transmission Rate (MVTR). This test measures the rate 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 pass up to 3000 grams of moisture vapor per m2 of fabric in a 24-hour period. The higher the MVTR value, the better the fabric breathes.
Breathability - Exercise
>3000 g/m2/24h - Light exercise, such as normal cycling
>5000 g/m2/24h - Heavy exercise, such as hard cycling
It is important to keep in mind that breathability measurements are affected by factors such as fabric construction, thickness and any coatings or treatments applied to the fabric. In addition, individual perceptions of breathability can vary depending on your activity, environmental factors and personal preferences.
