## Our verdict

### Reasons to buy

-   Durable and high quality materials are used in creating this bag which tells us that this bag is gonna last you a long time.
-   Massive capacity with 45L
-   Highly water resistant so you don't have to worry when it starts drizzling.

### Things to consider

-   It is isn't used as a daypack bag because of its size.
-   Doesn't have any tech compartment.

## What reviewers said

-   "It's the best bag for people who travel like me: you can run through the airport with it, you can hold it on your lap on overnight bus trips, you can use it as a pillow when you have to sleep on a dock, you can carry it up to ten flights of stairs, and you'll look sort of professional the whole time. What a win."
-   "I am extremely pleased with the Aeronaut 45–it still looks great and has worked out well for most of my trips."
