The DJI Mavic Pro is one of the most popular drones on the market. It comes with various batteries, props, and other parts, so you will need a decent bag to carry everything around conveniently. The Penna SlingBag can help. It is waterproof and lightweight. It has space for your headset, propellers, umbrella, beverage, iPad, and everything in between.
The Penna SlingBag has side compartments with pouches with batteries, cables, and other accessories. The main strap is adjustable from 27″ to 47″. Expected to ship in March. More info is available here.
