I purchased the Atlas to replace my existing aging travel duffel. The thing that stood out to me the most when considering the Atlas as a replacement was the vastly superior organization offered by the Atlas. One of the things that frustrated me the most about my previous duffel was the absolute lack of organization. Both bags are roughly the same size (90L on my previous bag to the Atlas' 95L), but my previous bag was just one big black hole for the main compartment with no dividers or straps. The two full-length external side pockets also had zero organization; just two big long pockets for things to slide around in. The Atlas solves these issues. The customizable main compartment dividers are a godsend. The Atlas' bottom compartment has internal straps for securing contents which is very handy and having three external pockets per side makes organizing and accessing all the stuff I have to haul around with me so much easier.
Another win for the Atlas compared to my previous duffel is serviceable wheels. The hard rubber tread on one of the wheels on my previous duffel disintegrated about two years ago and I was just stuck with one in-tact wheel and one bare plastic wheel and no way to replace it without replacing the whole bag.
In my use of the Atlas so far, the only downside I've found compared to my old duffel is that it won't stand up on its end without being leaned against something (useful when the handle is extended and you need to set the bag down momentarily to do whatever—you don't have to collapse the handle and set the bag down flat or lean it against something, you can just stand it up). By no means a deal breaker, but I do miss that capability.
All that having been said, I would highly recommend this bag for someone who travels frequently and needs to haul 10-14 days worth of clothes and things around with them while they're in the field.
Just like all the other Eberlestock products I own, quality is absolutely top-notch! Very satisfied with this duffel!
TLDR: The Atlas Duffel is an excellent rolling travel duffel with superior organization and top-notch quality that I would highly recommend to anyone in need of a bag to support 10-14 day trips.
