Quilting works by trapping air in pockets between two layers, which is why a quilted coat is warm out of all proportion to its thickness and why it does not shorten a dog's stride the way a bulky one does. This one wraps over the back and chest with a simple buckle fastening, cut for medium and large breeds on cold, dry walks through the worst months of the year.

There is a reflective strip built into the coat, which is worth a good deal more than it sounds between November and February, when most dog walking happens in the dark either side of work. The tailored shape sits along the back rather than bunching at the shoulders, and a buckle means one movement to fasten rather than wrestling with straps in the rain. Silver grey also shows road dirt less than a pale coat would.

On weather, and on sizing. This is a warm coat rather than a waterproof one, so for persistent rain you want a raincoat, and this is better suited to cold dry days and frosty mornings. Size it on your dog's back length from the base of the neck to the base of the tail, and on chest girth, rather than on weight.

What the options mean. Sizes run from S to 2XL — £19.99 for the smallest, £23.99 for the largest.

Who it's for: Owners of medium and large dogs walking through a British winter who want warmth and visibility without a heavy coat.
