Umpqua UPG HD Medium Midge Fly Box Blue, One Size

You probably wouldn't call a midge heavy duty, but you can give your selection some heavy duty protection in the Umpqua UPG HD Medium Midge Fly Box. A two-sided, magnetic, swing-leaf insert allows you to separate all of your flies by type, and the box is Class 3 water-resistant so your dries stay dry while you wade. You'll have an abundance of flies to choose from, thanks to this box's FlyTrap High Capacity Storage, and two insert types--TPE Micro for the littles and a magnetic option for your standard flies.
