Fantastic Bag!
The Aeronaut 45 is excellent for airline travel and fits in the overhead bin nicely! I recommend it for trips that last from 5-7 days and don’t require a ton of outfits. This bag is usually my go-to for conventions and it has never let me down.

I was looking for another type of luggage carrier when I went to Japan with a suitcase and a duffel bag
It took a trip to Japan for me to realize I needed this Aeronaut 45 bag.
Experience there was great except for when I had to drag my luggage through train stations and up/down stairs.
Aeronaut 45 is roomy and comfortable as a backpack, which was exactly what I was looking for.
Padding in straps provides comfort. While the different compartments make storage a breeze.
Packed a weeks worth of clothes in the main compartment and there's still space leftover. Also treating it as my emergency bag in case something like a fire or earthquake happens.
I bought the purple (aubergine) one once it was in stock again.
Can't wait for my next trip!
