We don’t call this box the most innovative fly box ever built for no reason. From its waterproof and breathable nature, to the silicone mat and anchoring system, this box not only looks amazing, but it is packed full of functional innovation. Previously, waterproof fly boxes only kept water out. We’re all guilty of putting wet flies back into our boxes, but the breathability of eVent Fabric allows moisture to dissipate and escape. The inner gasket forms a precise seal, keeping water out, and delivering the first latchless closure system on the market.
