Pelican Air cases are the first in a series of remarkable innovations engineered by Pelican, the pioneers of protective cases. For over 40 years Pelican has designed and crafted the most influential protective cases in the world. Pelican Air cases are designed to be just as durable as their heavier comparison.

The Pelican Air Case has been designed to cut weight without compromising durability. Pelican''s engineers have revolutionized the protector case by reducing structural waste while preserving Pelican''s legendary standards of strength. In development for years, the design team challenged the status quo to "add lightness" in every detail.
