This thread is over three years old so I am looking for updated advice.

We are looking for very lightweight (key parameter) rolling duffle or tote that we can take with us for short land trips. Needs to be easy to haul onto trains and put in lockers at train stations. We have a cheap samosinite rolling duffle that cost just $29 but it is not very sturdy; we want something that can hold a bit more, sturdy, and just as light.

thanks,
