The black Sling Pack from Porta Brace is a small, single strap pouch for over the shoulder use. It holds the small items that you always need but can never seem to find in the depths of your larger camera bag-tripod plates, small mics, batteries and similar sized items. It's also useful for quick access items such as two-way radios and cell phones. The interior divider system is adjustable to accommodate items of varying size.
