Product Description
The BrightLine Bags® D4 Quad Drone Bag is a ready‑to‑fly configuration designed for UAV pilots who need organized, mobile storage. Built around the CS4 Center Section, this kit adds the Pocket Cap Front for small‑item organization and the Pack Cap Rear so you can switch to backpack mode when you’re on the move. Choose the matching drone foam (sold separately) for the DJI® Mavic Pro, Mavic 2 Zoom/Pro, or Mavic Air 2 to create a secure, custom fit for your aircraft and accessories.
Two Side Pocket Charlies expand capacity for props, batteries, chargers, and field tools, while the included Main Handle and Shoulder Strap provide carry options when the backpack straps are stowed. With FLEX System compatibility, you can add additional center sections or swap caps to tailor the bag for missions, travel, or training days—up to and including multiple drone modules. Note: the CS4 ships with a divider shelf that is typically not used when a drone foam insert is installed.

I normally wear an xl for 95% of my shirts. I ordered a 2XL in this just to be safe. STILL too small. Sizing is crazy. You can do better. Charge me for a correctly sized shirt, I don’t care! But don’t do this.
I’m NOT taking a pic.
