The insert is  large enough to hold a substantial amount of gear, yet small enough to fit into an assult/3-day pack.

This organizer has many features both inside and out. On the outside, there are two handles on the top for easy hanging in either direction while it is closed or opened like a clam shell. There is also an easy access pocket on one side perfectly sized for a Flexi leash.

On the inside, this organizer comes with seven individual pouches that securely attach to large Velcro sections lining the inside. Two large mesh pouches, great for drying gear and helping prevent mold and mildew, measuring 8" x 8" x 2"; four small pouches measuring 4" x 8" x 2" with three being mesh and one solid, good for food items or those that don't need to be air dried.

All six of these pouches include a single zipper, small piece of Velcro on the front for a label and larger section of Velcro on the back for attachment to desired location within the organizer.

The seventh pouch measures 3" x 6" x 2" specifically designed for your dog's Doggles. It includes a pull-string closure and a clip on the top for easy attachment as well as a single MOLLE strip down the side for additional attachment options.

A single strip of MOLLE webbing runs down the inside of one side and a daisy chain down the inside of the other for multiple attachment options. One is great for attaching the Doggles pouch and the other ideal for securing a tracking line using the two Velcro strips threaded through the MOLLE.
