MATERIAL : Synthetic WATERPROOF : No Waterproof WEATHER CONDITIONS : GOOD WEATHER Quantity : 1 U Size : * How do you measure a fabric's quick drying capacity? : The product is machine washed 3 times then line dried, then we immerse it in water and measure how long it takes to get back to its pre-wash weight. This cap gets a very good score of 4 out of 5 stars returning to its pre-wash weight between 80 and 120 minutes following submersion Why have we used checked fabric? : The crosshatched fabric is a mesh-type fabric. The warp and weft design helps ensure durability and prevent potential tears and stop tears. It is therefore particularly durable compared to a smooth canvas, for example. Additional sustainable development information : By recycling plastic bottles to produce our polyester, we reduce the utilisation of oil-based resources while maintaining the material's breathability during sports practice.
