With Billfisher, we set out to create a product that would function as a tool for outdoorsman that focuses on function and Performance, not just aesthetics. It features our signature 4-Way Stretch UPF 30+ Next Generation Lightweight Performance Fabric as well as other features like Moisture Wicking Characteristics, things that outdoorsmen don't just want but actually need. Fit: True to size By combining Polyester and Spandex with state of the art knitting techniques, we've developed a UPF30+ fabric that provides for UPF protection without compromising breathability and Moisture Wicking characteristics. The Billfisher has a soft hand and will last incredibly long thanks to our proprietary knitting techniques. What we were specifically blown away with was the quick TTD (Time to Dry). We measured the TTD to be around <3 minutes, which is significantly faster than the 5-10 minute industry standard.
