Large Gray Bark Towel Chammyz fabric is "green" made from a special combination of the bark stems twigs and roots harvested from the Northern Canada lumber farms. This "waste" normally would've been burned or hauled away and buried. The way the fabric works is that you would wipe or dry off a animal person car etc. The fabric will absorb 9 1/2 times more water/moisture than cotton. Once the water/moisture is removed the Chammyz start an immediate evaporation process so in essence the Chammyz remain mostly dry. Only if actually dunked in water do they become wet and heavy. If or when this happens then all you have to do is wring them out. Cotton will remain wet and heavy where as the Chammyz will be almost %100 dry and will be back to a light weight material. The material is government tested and is %100 UVA/UVB rated an SPF of 50+ and hypoallergenic. As far as being green we've been awardedseveral stamps of approval. This is machine washable and dryable in hot warm or cold or can be hung to dry. These are good for at least 500 washes as well. Features Color - Gray Size - Large Dimension - 26 x 17. 5 x 1 in.
