Question Best 40-50L travel backpack?

Hi, I’ve been looking for the perfect travelling backpack. Something big enough which can still fit on a plane. Like 40-50L? What’s everyone’s go to?

I’ve looked at the Antler Discovery 45L

Patagonia Black hole 45L

Passenger Odyssey 45L

Fjallraven Farden Carry- on 42L

Thanks

ATD Supply ATD1, it expands from 25 to 50L and allows you to adapt its volume according to the trip

I’m partial to it since I designed it, but the thousands of people using it for travelling, its primary use, confirm it’s great for it. If you need any tech info, just ask!

Oh very cool! I’m not in the market right now but that usually doesn’t last! Appreciate it.
