Waffle knit is the fabric of a thermal vest, and it works on pets for the same reason it works on people. The raised grid traps a layer of still air against the body without adding weight or bulk. That makes this a genuinely useful indoor layer for a short-coated dog or a cat in a cold house, rather than something you wrestle on before heading out into a January downpour.

The cut is a simple sleeveless vest with a stretchy body that pulls on over the head and settles without needing adjusting every ten minutes, finished with a small embroidered bear patch on the chest. It comes in four colours across five sizes, and weighs between 25 and 58 grams depending on which you choose. That lightness is the real test of any pet garment, because it is what decides whether a cat keeps it on.

Not a winter coat, whatever the category says. There is no lining, no padding and no water resistance. It is a knitted top for indoors and mild days. If you need something for a cold, wet walk, buy a lined coat and keep this for the house. Size on chest girth and back length rather than weight.

Who it's for: Small dogs and cats who feel the cold indoors, and anyone who wants a light everyday layer rather than outdoor kit.
