This isn't really a review-review. Not yet. That will come later... after I actually use the SE as I intended when purchasing it-- as the ultimate one-bag carry-on for a month-long trip to Indonesia to help catalog a library... CAN'T WAIT (for the trip or for using the bag that way!) I love that there is well organized room enough for a change or two of clothes to be with me as well as separate space for water, notebooks/pens/snacks/book/docs, etc... all in one compact (all considered) bag...and not have it jammed full, weighing its max. Suitcase and a personal item all in one...tuck a MCB into the checked bag...good to go.
Most of the other trips I might take in a year are only going to be 4-5 days and I can imagine using the SE as the only bag for those shorter trips... awesome.
BUT, beyond using it for travel... This thing holds it ALL when it is raining...which it has been doing one heck of a lot of here this last month. I throw in my work shoes, a MCB filled with the daily assortment of whatnot, laptop and cables, umbrella...and much more would fit besides. I could put all in the MCB in other compartments of the SE, but I like having something smaller to move with me throughout the day.
