If the past couple of humid days are any indication, the complaints and celebrations are about to begin: it’s summertime in the city. With summer comes travel, and that can mean anything from a day at a sandy beach in Toronto to afternoons at a park or a rooftop pool to weekend trips to northern cottages. All of these things require a good bag, and it should be big—how else are you going to carry mason jars full of bourbon cocktails to the park with your picnic rations, a football, a portable iPod dock and doggy biscuits? (Please don’t carry your pup in your bag, because it has legs and wants to walk.) We searched far and wide for a selection of bags that can suit the sweaty jock, the camper who insists on packing a pair of heels, and the leisure traveller. Check out 10 duffle bags that will fit all of your things for whatever occasion—again, they will fit a small dog, but please avoid looking so foolish.
