The lightest, coolest, most wicking flannel you've ever seen – not heavy or warm. We’ve taken this outdoor basic and reinvented it to keep you cool and dry when you're active, while doing the Earth a favor. Of course, Oysterous Flannel has the same cotton-soft feel and comfortable flex that’s made Duluth Flannel famous. But Oysterous Flannel sets a high water mark in performance thanks to a blend of super-strong polyester made with recycled oyster shells. The result is a comfortable, breathable shirt that wicks moisture and fights stink like no standard flannel can. A snap front makes for speedy dressing. Reach Gussets® give you freedom of movement whether you’re raising a rafter or a poker bet. There’s even a glasses chamois to shine your sunglasses. Slip one on and you’ll feel like the world is your oyster!
