Helikon-Tex Bushcraft Line, Bushcraft Satchel

Would this bag be good for daily work life? Like carrying planners/schedules, documents, ect?

I love my bag. A small critter chewed through the main zipper on 1st trip. Im heart broken. Any way to have repaired? Ive only had it a few months.

A design flaw?: no top flap (just an exposed zipper). Has anyone actually used this bag in a day of hiking in the rain?

What are the dimensions of the bag (L, W, D)?
