From the brand:
The quick-dry material is 100% recycled polyester. It is actually made out of recycled water bottles. It is very high quality and I am so happy with this new and improved fabric. The same print is on the front and back. Each bandana is handmade by Erin with love in Honolulu, Hawaii. Every one is unique and the placement of the patterns may differ. This secures with snap buttons at the following sizes. SIZING: Small - up to 12 inches Medium - up to 16 inches Large - up to 22 inches Snaps are placed at top of size.
