Are you a one trip operator? By that I mean do you simply do one walk from your car to the kitchen with all the shopping bags? If that's a yes, or yes I want to be a one trip operator then feast your eyes on these badboys. Capable of carrying up to 25kg (tested). That's a grain sack in each hand. Go beast mode with KegLands Yellow Market Bags. 
Not to be confused with similar bags you might find at that small place down the road... IKEA I think they call it. 


Dimensions:
580mm Wide x 450mm High x 150mm Deep
Two sized strap handles. Shoulder carry or Bag Handle Carry

Keep out of direct sunlight as it will weaken the bag over time.
