Breathable  
Breathability is a term used to describe the textile’s ability to transport moisture and is determined of how easily the vapour can pass through the fabric.  

Warm clothes is not enough for outdoor activities. Breathable outerwear absorbs and releases moist so your child can “breathe” in it. The higher the number, the more breathable the product is. As every child is individual, breathability can vary depending on climate, activity level, fluid intake and sweat.
