Specifically designed for project site environments, this YRF 30% wool blanket has a size of 200x100cm. Despite a 30% wool content, through careful material selection and craftsmanship, it achieves a good balance between being lightweight and heat - retaining. Weighing only a specific amount (assumed to be 500g, adjustable according to reality), it is convenient for workers to carry. It can effectively resist the cold during breaks at the project site, providing a warm resting guarantee for workers after hard work.
