Aeronaut 45 Key Features

Three-Way Carry, Maximum Versatility

Three carry options adapt to any journey — backpack, duffel, or shoulder bag — all designed to keep you comfortable and moving with ease, no matter how you travel.

Pack Easy, Adapt Instantly

Spacious main compartment opens wide for easy packing, with zip-away end dividers for extra room and a mesh pocket in the lid to keep small items in check.

Convenient Pockets, Seamless Grab

Two quick-access pockets on each end — grab earbuds to passports in a snap, even from the overhead bin.

Double Pockets, Cleaner Packing

Two roomy end pockets add much-needed compartmentalization — perfect for separating clean from dirty or shoes from clothes, fitting up to a size 12 pair comfortably.
