Umpqua UPG Fly Box - Foam Waterproof Ultimate Nymph Large

UPG Foam Tailwater Fly Box (Tan, Mini)

Tailwaters are technical fisheries that demand versatility. One day it’s size 24 dries and midges, the next it’s size 10 leeches, plus all the right shades of sow bugs, scuds, and emergers in between.

The UPG Foam Tailwater Mini Fly Box is designed specifically for that kind of fishing. It delivers fast access for tiny flies while still giving you enough capacity and organization to carry larger patterns—making it a perfect compact option for tailwaters, spring creeks, and picky trout water.

When the fishing gets complex, this box keeps it simple.
