well you could try utah then they have 2 smaller bags (1 boxy and 1 flat pouch) and a messenger type smaller bag in it ( I cant recall the names). If you can find some and want a bag thats alot more casual some of this year's LV cup bags like solent might work but the solent is very small for alot of people, mine fits all my stuff (but is packed) and I carry a fair bit (watercolor kit, pens, small sketchbook, wallet, keys, sunglasses) and might be too casual for work. I do like the citadin though although I have never been a fan of the DG material or bags as they dont seem to have enough accents for me.
