Free Fly Men's Seawool Flannel Shirt

Anglers who want a flannel that behaves more like a fishing shirt tend to land here. Free Fly’s Men’s Seawool Flannel Shirt uses Seawool fabric, a midweight brushed twill made from upcycled oyster shells and recycled plastic bottles. The payoff is comfort that stays steady when the day swings from cool mornings to warmer afternoons, plus quick-dry and anti-odor performance that matters on travel days.

Across the sizes we carry (M through XXL), the material and feature set stay the same. The choice is simply how much room you want. This is a performance flannel first, not a heavy, wind-blocking overshirt.
