A lot of the ones I liked the look of were heavy. Or didn't meet my organizational preferences. The Patagonia isn't perfect for me, but is getting there.
First, the GoLite. Three external pockets, with no internal organization. Very useful to me, can pack meds, cables, even fit a lightweight rain jacket in one. Also a well-placed, well-sized passport/ticket pocket not shown.
Interior is black which is not optimal to find things. Main compartment is two compartments. I like this at the end of trips, as one side is dirty, the other clean.
Both covered with mesh panels, so easy to just toss stuff in, and you can still get to the other side or even store a folded sport jacket between the two sides.
Construction is too clever by half, so when it started to fail, no way to get to the seams to reinforce or repair them, and not enough material on handles and straps past the attachment so nothing else to sew to. So, it's a goner.
The two bags are the same basic exterior size, have similar handle and almost identical shoulder strap arrangement, so that's nice
This is all unpacking from a trip, so I got some experience on the Patagonia. Reviewing as much of this was unclear before buying. Not enough photos, walkthrough of features, so now you all know.
Outside in: There's a much larger flat document pocket. Probably too large for document retrieval when needed, but it is what I use it for now still.
Construction is finished and neat with straps running into seams, but tends to have load bearing on reinforced bar tacks. If they manage to fail, detectable before it goes too far, and repairable.
Next is a half-opening compartment of organizers. I don't love this because half-opening means it's hard to organize well. I presume it does this so stuff doesn't fall out, but it's a soft bag, so cannot really be used upright, so flopping open would be better. I do not use this as well as I could, or maybe later will.
Interior is orange/red. Easy to find stuff!
Next zipper down allows it to flop open flat.
Top is complex. There's a perimeter (double) zipper which is a flat compartment which actually works well to expand and store clothes. My clean end-of-trip clothes went in here. Worked better than it seems like it should, and I could put a lot more in here if needed.
The lid of that pocket has two pockets, one solid, one mesh. I do meds / toiletries in here for now.
The other half is a deep compartment with a mesh zippered top, where clothes go.
It has a distinct overlap which I thought was stupid at first, but helps give it shape, and helps you pack it square. Despite being lightweight, it has structure and shape. If you don't load this compartment to overflowing, the shape persists, and the other side of the luggage protrudes into the space, so the overall bag doesn't bulge.
Folding it back up, the back side has one more useful pocket. It needs to store relatively flat things, but I can keep a fleece pullover in it without messing with bulging the luggage. Rain coat could also be folded, but not stuffed, into here.
The remaining zippers are Value Add Features. There's an open-top pocket of no use, and a zipper on the bottom. If you have this as a secondary bag to a roller with wheels, you can unzip and slide the tunnel over the handle. I have an equipment case with a handle, but try not to go long distances wheeling it, so haven't use it yet.
The handle end has a zipper to conceal the shoulder straps. This is as much as I have seen of them, but they are there.
Price wise, I got this exact model and color from Amazon for $179, and it still shows that price. Other colors (and other stores) are more expensive, or out of stock. I have found people trying to sell them for $400. Totally, unreservedly worth it for that price.
