We love this heavy duty canvas bag with all it pockets.  You can carry it chicly with its  handle on your forearm Japanese style or carry with handles.  But this small tote is all about the pockets - 5 of them outside and 4 of them inside.  You will be stashing things everywhere, we have tested it and the Kinto tumblers in fact do fit perfectly.   

Use for gardening, check, your everyday run around bag, check, bring my bag to work, check.  The inner pcket holds a4 paper so if you have a small laptop or iPad , check - how about you put a magazine in that pocket. We really can't choose between the small and large, the large is well larger and has a shoulder strap,  we think one of each in different colors will fulfill our every casual bag need.
