My New Go-to Euro Single bag travel bag!!
Purchased this bag after reading a zillion reviews for light packing to Europe. the Techonaut30 is perfection! Light, easy to pack and holds alot more than you think with excellent build quality. Very east to use and comfortable to carry!! No question worth the extra few dollars it cost

Super comfy and holds quite a bit
I think you get exactly what you’re expecting with this bag. It’s extremely comfortable, obviously great materials and a big plus is it’s not as bulky as some photos might lead you to believe when it’s on. Haven’t taken it on a trip yet but super happy with it and what it has done so far with all my test packing. It is very expensive but I don’t regret it.

Simplicity
This is a travel bag - not a backpack. It's beauty lies in its simplicity. There aren't a hundred little pockets, there's one big area with a few pockets on the side - plus an extra area at the bottom - perfect fit for a pair of shoes. But even the divider to that compartment can be zipped down , adding to the overall space in total.
With the backpack straps or without; with the shoulder strap, or without - its carrying options make this the most versatile packing system you'll ever have.
