My husband bought this bag for me.  It is fabulous - I researched back packs and I was convinced I needed a Tumi bag but the more I researched and also did some field research (Checking out and chatting with my fellow travelers) I determined that the features I sought may not align with the Tumi product offerings.  I didn't want a bag that was delicate (non-leather) and that wasn't super hiking oriented.  This bag is sturdy, professional, well appointed with organizational features and trollies well.  It is also 80% less than I thought I would spend.  I did take heed and removed from my previous Tumi bag laptop bumper and placed it in the bottom of this bag when I received it.  I don't always say my husband was right - but he was - the research and thoughtfulness paid off - this is my best product choice in years ....
