Boat Box Ultimate Sage – Umpqua Feather Merchant
The Umpqua Boat Box Ultimate is the workhorse of the Boat Box series — sized for a full day on the water without the bulk of the Magnum. At 13" x 10" x 3.5", it holds enough patterns for any hatch, any run, any condition, while staying manageable in a boat bag, sling pack, or dry box.
Like all Boat Boxes, the Ultimate features slotted foam on both interior lid panels and a dedicated external slotted foam sheet — the feature that separates this box from everything else on the market. Stage your next rotation, dry freshly used flies, or grab a pattern on the fly without ever opening the main compartment. Behind the oars or wading a run, that matters.
Key Features
- Slotted foam on both interior lid panels (top & bottom)
- External slotted foam sheet for drying, staging, or quick access
- Fly placement guides molded into foam for easy slot identification
- Thick, durable foam construction built for repeated field use
- Sage colorway — clean, understated, and guide-ready
Boat Box Series Dimensions
- Baby — 10" x 8" x 3"
- Ultimate — 13" x 10" x 3.5"
- Magnum — 16.5" x 12" x 4.5"
