The Treefort Lifestyle Slack Pack Waist bag was designed for enhanced functionality. This fanny pack has a bit more room so you can bring more of what you need without needing to lug around a big backpack. The main compartment is a large zipper pocket for a water bottle, camera lenses, found seashells, or other valuables. A smaller zipper pocket in the front was made for money, keys, pen or pencil, or smaller item. On the back of the waist pack is a slip pouch for a phone, notebook, wallet, or any accessory needing easy access.
