We have finally developed a much easier fit in our signature upcyled cotton that comes in two sizes! The beanie fit is a lot more versatile than the watch cap, but as with the watch cap, we do not recommend the cotton yarn for extreme temperatures, cotton is not a heat retaining natural fiber. Please see the Ragg Wool beanies, mohair, or upcycled wool wathcaps for a warmer, high Winter, hat. What is Eco-cotton? Eco-cotton is a blend of reclaimed cotton fibers from discarded garment scraps combined with a small amount of polyester made from the incredible RPET process of recycling plastic (PET) bottles into fiber.
