# The Best Waterproof Fly Boxes Source: https://flyfishnest.com/best/best-waterproof-fly-boxes Updated: 2026-09-15 Publisher: Fly Fish Nest. Our score is an editorial rating out of 10 (fit 35%, features 25%, build 20%, value 20%), not a customer rating. Method: https://flyfishnest.com/how-we-research#our-score A soaked fly box costs more than the annoyance of wet foam: rusted hooks, matted hackle, and clumped CDC can ruin dozens of flies at once. Waterproof boxes solve this with gasketed seals and positive latches, but not all seals are equal. Boxes vary in how well the gasket survives grit and repeated opening, whether the latch pops open in a pocket, and how much capacity you give up to the sealed rim. We evaluated seal reliability after real field use, latch security, foam quality, and whether each box floats. Wade anglers who fish deep or fall in occasionally should treat a waterproof box as mandatory for their best flies. Boat anglers benefit too, since rain and deck water find everything eventually. If you fish mostly dry conditions a standard box may serve, but the price gap is smaller than it used to be. ## Picks ### 1.
