The Overflow Mesh Pouches were designed to be mounted to the interior of any Vertx bag or other hook and loop compatible surfaces. The back to back zipper pulls enable easy access no matter what direction you set the pouch in. The abrasion-resistant mesh provides durable protection and fast visual identification of stored items. The large mesh pouch is ideal for larger medical or first aid essentials, maps, laptop cables, small clothing items and other larger items.
