The Mover Pack is an affordable duffel with simple backpack straps, solid materials and a few solid pockets for organization.
They’re actually surprisingly comfortable. I, personally, like to travel with a travel backpack due to their robust straps, optional hip straps, etc.
But as far as an affordable duffel with backpack straps goes, this thing is solid. (And bonus for it not looking like a big, sticky, rubber patagonia or north face bag.)
The material and zips and organization all feel surprisingly solid.
Other Bags to Check Out:
The Travel Duffel from Aer is an excellent "trunk style" duffel bag, but with a whole smattering of modern travel tools like laptop storage, water bottle storage, and tech organization.
The ATD1 is an expandable backpack you can use for both travel and daily carry. Looks pretty damn good too. One of the best in this category for sure.
The Headway MLC (Maximum Legal Carry-on) from Patagonia is a very functional gear bag that works better as a duffel due to it's uncomfortable (but hideable!) backpack straps.
The Viken from YNOT is as simple and sturdy a duffel as a modern urbanite could ask for. And it expands. Just lovely.
