Umpqua Boat Box Magnum SAGE | Large Fly Storage for Streamers & Big Flies

Maximize big-fly storage on the water

The Umpqua Boat Box Magnum SAGE is built for anglers who stash large flies and streamers for long days on the water. Its rugged shell and thoughtful foam system emphasize easy access, secure organization, and quick drying, so you can focus on your cast rather than rummaging through gear in rough conditions.

The standout feature is a three-layer foam layout: slotted foam on the top lid and the bottom, plus an external slotted foam sheet. This configuration makes it easier to see where each fly slot sits and to grab what you need with one hand, even when the boat is moving or you’re standing in chop.

• Ideal for streamers and other large flies
• Internal slotted foam on top lid and bottom organizes flies securely
• External foam sheet for quick organization with one hand
• Fly placement guides on foam to easily locate slots
• Foam sheets on interior and exterior of boat box

Designed for anglers who value organization

The Magnum SAGE offers generous space without sacrificing accessibility. Measuring 16.5" x 12" x 4.5", it accommodates a broad lineup of patterns while keeping them protected from jostling. The thick foam cushions each fly, and the external sheet serves as a staging area for quick access or for laying out flies to dry after a day on the water.

• Keeps big flies visible and easy to reach during casts
• Two foam surfaces plus an external sheet support flexible drying and organization
• Durable materials withstand rain, splash, and miles of travel
• External sheet dries quickly, helping gear stay ready for the next cast
• One-handed organization behind the oars minimizes disruption to your line

Real-world use often means a crowded boat, moving water, and sudden wind. The Magnum SAGE aims to simplify your routine by providing reliable slots and guides that help you locate a pattern at a glance. While outcomes vary with technique and conditions, having a dedicated system for big flies can make a noticeable difference in how efficiently you switch patterns and maintain fly quality in transit.
