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.

While I have purchased many Free Fly items over the past two years since my dermatologist recommended the clothing line to me as a way of protecting my skin after a bout of melanoma, I have now started expanding my clothing choices by purchasing the Men’s Seawool Flannel Shirt line. I love these shorts in that they are both soft and comfortable and yet dressy enough to wear out and about. I have tried competitors shirts, who will remain nameless here, and they simply don’t match Free Fly in quality and fit. Do yourself a favor and buy try one of these shirts. You won’t regret it…

This is the most comfortable flannel I have. Very soft and love the fabric. I also hae Kuiu flannels, and i like this one more because it has a little bit of stretch to the material and the softness is the best yet.

Very high-quality flannel with a perfect fit. The material is not too thick, so it can be good for somewhat warmer days. I pair these with the Tradewind Pant, and get nothing but compliments.
