A light weatherproof jacket is always handy anytime of year when dog walking but with leads, poop scoops and a dog toy, you can quickly run out of hands!
The ‘Jacket Bag’ is perfect as you can clip the bag round your waist and store all your odds and ends in the three zipped pocket, or the accessory pockets for water bottle, toys etc.
Then when it starts to rain five minutes into a walk, as it invariably does, you simply deploy the stitched-in weatherproof jacket with hood from the bag.

If you have a dog, you definitely need a Jacket Bag
