Vanguard's VEO Select 42T is a compact and well-designed roller trolley that easily converts into a shoulder bag. It's compact and slim profile can be deceiving as it is able to carry a lot inside. Using the customisable foam dividers, this bag with carrying up to 1-2 pro DSLR/mirrorless cameras (with their grips attached), 7-8 extra lenses (up to 300mm f/2.8), a Speedlite, a 16"" laptop, a 9.7"" tablet, up to two tripods and all your accessories from multiple memory cards, cables, batteries and a charger. That's a lot of gear. What's great is the bag meets the onboard size and form of most major airlines, but of course, always check with your airline first!
