Why flannel? 100% cotton flannel is a woven fabric that is napped (brushed) on either both or one side of the fabric. This napping creates flannel's insulating properties, also softness and in turn comfort.
Why Japanese flannel? I devoted a few years to experimenting with various fabrics, searching for a material that could match the durability and comfort of LL Bean chamois but with a more refined texture. These styles weren't suitable for use with thick fabrics. When I discovered this flannel, I was truly impressed by its durability, exquisite softness, and perfect weight and texture.
Fine and durable fabrics are the most sustainable choice because they last and wear well over time.
