Umpqua UPG Sili Essential Fly Box Double Large Blue – Silicone Dual-Sided Storage for 8–22 Fly Sizes

Meet the UMPQUA UPG Sili Essential Fly Box Double Large Blue

The Umpqua UPG Sili Essential Fly Box Double Large Blue combines a slim silhouette with two dedicated sides to expand capacity without adding bulk. Built for dry flies and nymphs in the 8–22 size range, this dual-sided box helps you carry a broad variety of patterns ready for quick substitutions on the water.

Two separate faces give you flexible organization so you can group dries on one side and nymphs on the other, or sort patterns by color, pattern family, or date of tie. The FlyTrap feature minimizes head and tail overlap, making it easier to pull out the exact fly you want without disturbing others. Angled entry points guide flies into their slots, speeding up reloads between casts and covering long days on the river with less snagging and fumbling.

The box relies on a deep gutter system that protects fully hackled flies, preserving their shape and keeping them in prime condition from the moment you pack up to when you reach your next run. The silicone is described as zero memory and self-healing, delivering a durable, long-lasting surface that reduces sticking and maintains a confident grip even when hands are wet. The shell itself is lightweight and ultra-slim, yet it stands up to field use with an impact resistant exterior and a magnetic quick access opening that makes loading and closing feel fast and tactile.

In practice, the Double Large Blue model offers a practical balance of capacity and portability. Expect a compact box that still accommodates a sizeable selection of dries and nymphs, a secure hold that keeps patterns from shifting during transit, and a simple workflow that helps you stay organized as water conditions change. This is a versatile option for anglers who want to keep multiple patterns neatly separated and readily accessible without carrying a larger, heavier box.

If you value a tidy, field-ready system that respects fly integrity and reduces handling time, the UMPQUA UPG Sili Essential Fly Box Double Large Blue is worth considering. It presents a thoughtful mix of organization, durability, and ease of use, offering potential efficiency gains without promising specific outcomes.
