Guideline WP Slit Foam Swing Leaf Fly Box
The Guideline WP Slit Foam Swing Leaf Fly Box is the largest and most versatile model in Guideline's WP (Waterproof) fly box series. Featuring an innovative hinged Swing Leaf insert, it provides exceptional storage capacity while allowing anglers to organize multiple fly categories inside a single waterproof fly box.
With a total of 36 rows of precision slit foam, a waterproof silicone gasket and a durable ABS construction, this fly box is designed for anglers who prefer carrying their complete fly selection in one place. Guideline describes it perfectly as "One Box to Carry Them All."
What is the Guideline WP Slit Foam Swing Leaf Fly Box?
This waterproof fly box features three independent storage surfaces thanks to its removable hinged Swing Leaf insert. The center leaf is mounted on sturdy hinges, stays securely in position while in use, and can easily be removed whenever maximum internal space is required. This clever design delivers outstanding fly capacity without sacrificing easy access or organization.
The deeper compartment is ideal for bulky dry flies and parachute patterns, while the shallower side and the Swing Leaf are perfectly suited for emergers, nymphs, spent spinners and other low-profile flies. This makes it easy to organize flies by hatch, fishing technique or season.
