The JMC XP501 is a watertight, extra-thin box designed for fly fishermen looking for compactness, lightness and maximum protection. Its rigid ABS design guarantees strength and durability in the field, even in difficult conditions, and features a pre-cut high-density foam bottom, ideal for the organized and secure storage of dry flies and nymphs, while preventing them from being crushed. Its extra-flat format makes it easy to store in a vest, saddlebag or wader pocket, making it the perfect box for mobile anglers who want to protect their rigs while optimizing available space.
