Umpqua UPG Fly Box - Foam Waterproof Essential Large

UPG Foam Waterproof Essential Fly Box

Power Grip Foam + Essential Insert | Large

The UPG Foam Waterproof Essential Fly Box is an everyday workhorse built for anglers who want simple, high-capacity organization in a truly waterproof, pack-ready design. Available in Medium and Large sizes, this box is perfect for storing a wide range of dry flies and nymphs, from local summer wet wading to destination fishing abroad.

The Essential series is designed around one goal: maximum capacity, fast access, and secure fly storage without overcomplicating the layout.
