Umpqua's entirely evolved line of UPG fly boxes gives any angler multiple features, options and configurations through their flexible designs.
The Big Differentiator, it the new Injection-Molded Fly Sheets.
Injection molding versus traditional die-cut sheet foam gives Umpqua infinite possibilities in all three dimensions that will have you trading in all of your fly boxes. Here's why:
Extreme Gripping Properties - Thanks not only to the density and low memory of the material itself, but also to a unique slit-cutting procedure during which the slits are cut when the material is curved. The result is a tighter grip.
Unique Formats - Unlike die-cut foam, this new injection-molded material allows for 3D design resulting in formats that have never been seen before in fly storage.
Lighter than Comparable Inserts - Smart tooling design reduces material use. (TPE is lighter than silicone)
Slim, single-sided boxes with magnetic closures make these the perfect boxes for those who like high visibility, exceptional fly grip and easy organization.
I use these and tacky fly boxes. Why? The quality of the rubber and the hold that they provide. There is no doubt that flies will stay in place and will stay organized.
Seems very durable and the plastic feels smooth and high quality.
Lots of storage and the grid is well laid out.
