Pelican cases have long been the built-like-a-tank workhorses for hauling camera and video gear. Unfortunately, "tank-like" usually also means back-breaking. With its new Air line, Pelican has reengineered its cases -- though, oddly, not redesigned them -- to be up to 40 percent lighter.
As many manufacturers do when they're trying to make rigid structures lighter, Pelican honeycombed the body wherever possible. That can reduce mass without sacrificing durability. The company also switched the material from Polypropylene to a custom polymer, dubbed "HPX2", that helps absorb shock. To give you an idea of its strength, I stood on it without crushing it.
The 1535 Air Wheeled Carry-On I got to try out is about 28 percent lighter than its older equivalent, the 1510 Protector. These models are the largest versions that will fit in an overhead bin. The approximate 8.7-pound (3.9 kg) weight makes a big difference for me compared to 12 pounds (5.4 kg) for the 1510 -- I can carry this one and lift it over my head -- and if you ship gear in volume, the savings will likely add up. It's more expensive, priced at $250 (around AU$325 or £175, converted), though the new padded divider system doesn't cost extra.
To extend the trolley handle, you lift up a release and pull the handle out. I prefer being able to release and retract with a single hand, as that usually all I have available while going through security or boarding a plane. But that may just be me.
