I purchased my Ravenna in the summer. It looks like the one in the link, so I'm guessing it's the newer one. I had used a bigger school ? backpack I got from Costco many years ago. It is still going strong. This was for my personal bag. I usually packed it very full and it was consequently quite heavy, and tight to get under the seats, especially upon return. I got the Ravenna because my daughter said she wouldn't travel with us if we didn't go to lighter bags (my husband didn't, but did not pack his as full this time). We love the Ful packs, although the chest latches have broken on at least one. Downside, they do not have a sleeve for over the suitcase handle
I used Ravenna primarily for flight transit, and use in the car, so I can't address touring with it. It was my personal item and fit nicely under the seat. I did often put it on my suitcase handle.
I like all the pockets to organize many things. I actually didn't use all the items I had packed, but I liked having so many pockets. I didn't like that it doesn't have a bottle holder, but I used one of the zippered side pockets for a disposable water bottle. I just couldn't zip it across the top. I think I also had the bottle inside sometimes.
I'm happy with the size and sturdiness of the pack for how I want to use it. I would definitely use it as a pack on a bus, but would probably leave it on the bus and use a lighter, foldable bag for bottle, packable jacket, and a maps or guidebook for walking around. Or I would use my cross body purse for maps, glasses and packable bag.
I've only used the pack on one trip so far. Perhaps I'll discover next May that it works well for a long day out in London, especially if I might be purchasing picnic food or items at a market (but would expect to check it at museums). I also usually carry packable shopping bags which worked well this fall when I picked up woollens, framed photos and a puzzle in charity shops.
I like having lots of options even on one trip, but I may need to scale back if we will be moving around a lot or on a lot of public transportation. We only do carryon on the trip over but sometimes check on the return.
All in all, I am happy with my purchase of the Ravenna. I need the lighter pack for my aging body!
