McKinnon Camera Cube Pack 21L

Nomatic McKinnon Camera Cube Pack 21L — The Two-in-One for Traveling Photographers

The gist: A clever hybrid that collapses into a 7L camera cube for stowing inside a larger pack, then expands to a 21L backpack when you need to roam independently at your destination.

• Ultralight build: Just 1.36 lb (0.6 kg) — barely registers when stuffed inside a carry-on or checked bag.
• Convertible format: Collapses to a compact 5" × 13.25" cube; expands to 17.5" tall when you want a standalone daypack on location.
• Mirrorless-optimized: Fits a mirrorless body, prime lens, medium zoom lens, and accessories with customizable dividers to lock everything in place.
• Weather-resistant materials: Nylon and polyester shell with Zoom zippers keeps rain and splashes from reaching your gear without adding bulk.

Pack Hacker rated the McKinnon Cube Pack 7/10 and called it “great if you want a dynamic camera pack for trips that don’t require a whole photo kit,” noting the convertible system excels for mirrorless travel builds.

Best for: Travel photographers and content creators with mirrorless kits who want a camera carry solution that vanishes inside a larger bag. Skip it if: You shoot with a full DSLR system or heavy telephoto glass — the shoulder straps aren’t built for loads beyond roughly 10 lbs. Runs ~$130 — check the current price before buying.
