ODE to Box Calf

Dear all, help - would you take a box bag as your only bag for a trip in a quite mixed climate i.e. probability for rain each day 60% when you know you will spend time outside sightseeing and probably not being able to keep the bag completely from rain? Other option is my barenia bag which is of course worry free but the box one would be a perfect match to most of my outfits…. My box has not been treated in any way and is rather new so I am a bit nervous still for this one.

Which, to be honest, bothers me as I want to use the bag with out thinking too much as I do with all my other bags. But I also do not want to kill it off wittingly.

Any opinions appreciated!
Most all my H bags are Box. Absolutely no. Not with those weather forecasts!!
