When we returned from our last cruise, we had to throw away a medium sized rolling duffel that I've had for years. We had also, for the umpteenth time, sworn to get rolling backpacks. Backpacks make good carry-ons but tend to get a bit cumbersome and heavy - especially for me.
After much research we settled on High Sierra AT3 rolling backpack. We found the local Sears store had them in stock so we went to look. We not only bought the backpacks, which give us the bonus of a daypack, but the High Sierra AT3 32" Rolling Duffel. Stu got the dark gray and I got the red and we're really pleased with the bags. The 32" bag is bigger than our old luggage and will allow us to use one less bag on our cruises.
