I’ve been using this for a year now. I’ve been traveling 125-175 days a year for 15 years…..I’ve tried every bag/suitcase combo and could never seem to get it right. This bag with a Tumi international wheel aboard has been perfect. I can get all of my clothes in the suitcase and the TB25 handles everything else…computer or iPad…books, notebook, noise cancelling headphones. A couple small bags with stuff…electronics….munchies. AND I can stuff extra clothes – a based dress shirt…a pair of pants and underwear. In case I get separated from the wheelie, I’m OK for a day or two. And it’s indestructible. It shows zero wear after a years use and at least 20 countries. I’m sold. I’ll never need another bag for the rest of my professional career.
