💬 Reviewers Have Said

  • "Definitely gonna be using it when we travel again. Feels rugged enough to fling around, but secure enough that If I do fling it around my gear will be safe. The zippers feel tight and will resist a bit of rain. The pockets are nice. The organizer is great and the camera bag is a great design and integrates perfectly. Love it!"
  • "This backpack is extremely high quality and perfect for carrying all of my school supplies, tech essentials, and multiple meals for when I am on campus for the day. It is a little heavy but a good sacrifice for its great materials and features."
  • "I absolutely love this system. It's super comfortable to wear even all day carrying a heavy load and the modularity allows me to switch from a big pack to a small one with complete ease as a professional photographer. My only qualm is the lack of quick-release latches for the tripod carry at the bottom."
