A Moop Bag
I love big bags. The Moop Bag is a big bag. Actually, this bag is made by Moop and they are calling it a Market Bag. Moop have nine different styles of bags from duffel to clutch in their Etsy store. 
This Market Bag comes in grey, black, blue and sand but I especially like the rosewood color shown here. It is made from “corded canvas lined with red ripstop cordura”. You can see from the close up shots of the stitching at Etsy that it very well made. This eco-friendly bag is $93 and can be carried messenger style (my tendency) or over shoulder.
