Men's Seawool Flannel Shirt
Why You'll Love It
Don’t let the timeless looks fool you—the Seawool Flannel packs a punch in the performance department. Built from Seawool fabric, a midweight brushed twill made from upcycled oyster shells and recycled plastic bottles, these flannels deliver many of the same benefits as our powered-by-bamboo styles: they’re temp-regulating, quick-dry, anti-odor, and oh-so-soft. Bonus points: all those recycled plastic bottles never get the chance to end up in our oceans. Adventure-ready, sustainable, and classically handsome? Sign us up.
