Sustainable Flannel Shirts For Fall Layering
We đź’› Cozy Plaid Flannels
Flannel shirts aren’t just a fall trend. The style transcends seasons, and it’s easy to see why: These shirts are effortlessly cool, rugged, and comfortable. Flannels work anytime, anyplace.
That’s why this winter (and beyond), we’re stocking up on sustainable flannel shirts from our favorite brands. These shirts are created with eco-friendly materials like organic cotton, linen, and even fabric sourced made from recycled plastic bottles. Consider this shirt a sustainable staple for your wardrobe and a perfect pairing with your favorite American-made denim and ethical boots.
For secondhand flannels that are affordable, size-inclusive, and truly sustainable (because reuse is the new recycle!), check out Vintage Vanguard Co and Flannel Factory Vintage on Etsy.
