Content: 100% ECO-COTTON What is Eco-cotton? Eco-cotton is a blend of reclaimed cotton fibers from reclaimed garments & discarded cutting table scraps. Not only do these hats contain a percentage of recycled PET bottles but zero dyes or chemicals are used in the process of creating such vibrant colors from textile waste. Washing Instructions Spot clean by hand as needed. Lay Flat to dry. Source Knit in Waterloo, NY. Finished in Brooklyn. Size & Fit One Size Length: 11-12" Inches (without fold) Knit cotton is prone to stretch so if your hat feels a bit tight when you receive it, just a little wear will allow it to adjust to your head. Cotton is a lighter material, so these hats are meant to be worn as transitional hats. If you would prefer a warmer option, take a look at our Upcycled Wool Watchcaps! The watchcap is a style that's existed for well over 100 years, and is a shorter hat, traditionally meant to be worn folded above the ears. However, you can also wear it any other way!
