I got a Tumi T-Tech Continental Carry-on as a Christmas present this year. It was a sweet and thoughtful gift, and broke it in on my recent trip to Memphis.
After I opened the box and set up the TSA security lock, I read some comparative reviews, and man, people are really into carry-on bags! Before this, I was using a Herschel duffel bag (this one, actually), which was fine for a while. To carry it to the airport, I put the strap over my head and carried it on one shoulder or the other. The downside to that was obvious – my shoulder would start to ache before I got to the airport. But everything else was great: the size and durability, mostly. I also liked out it was made of nylon – I could always squeeze in one more item.
So now I have a hard-sided rolling carry-on, which is already a world of difference.
