I have struggled in the past with a fairly-heavy roll-aboard suitcase on wheels. Lifting it up into the overhead bin on airplanes was problematic and I worried even more about taking it down after the flight, afraid the weight would whack someone in the head because it was a bit too heavy for me.
I only use carry-on luggage, so something had to change.

But would I like a wheel-less suitcase like the eBags Mother Lode? That was the question.

The answer is YES! I took it on a 4-day trip to New Orleans. Having to carry all the weight on my back forced me to lighten up on my packing, which is always a good thing.
Because this is soft-sided, it easily fit into any of the overhead bins, no matter how small.

The total weight--with clothes, toiletries, a jacket, and an iPad--was 15 lbs.
I had no problem putting it into or taking down from the overhead bins.
And because it has padded shoulder straps, a sternum strap, and a waist belt, it was easy to carry around the airport.

Very well made, with lots of compartments and pockets. It even expands, should I need it.
Just a great travel bag for people who want to 'pack light' and I highly recommend it.
