Umpqua UPG Foam Essential Large Fly Box – Lightweight, Durable, Quick-Loading Fly Storage

Meet the UMPQUA UPG Foam Essential Large Fly Box

Designed for versatility, the Essential Large balances generous capacity with a slim, durable form. It’s ideal for carrying a wide range of dries, nymphs, and buggers, so you’re prepared for changing water, light winds, and varied hatch patterns. The box’s confident weight and low-profile silhouette fit neatly in pockets, vests, or packs, yet it won’t compromise on storage when the water is calling.

Smart storage that adapts to your day

Inside the box you’ll find an Essential Insert that keeps your flies accessible and organized. The FlyTrap creates offset storage to prevent head/tail overlap, while angled entry points help you load flies quickly without pinching delicate wings or hackles. The design prioritizes capacity and order so you can switch flies fast and keep your rig tidy.
