Heatgen strappy vest

Comfortable to wear. Not sure yet how it will be on cold dog walking mornings. At least it's long enough to tuck in back

Perfect for the colder months

Yes, I recommend this

Very warm and comfortable. It is a little long but I tuck the excess in trousers and tights otherwise it makes your tummy look big. The quality is great I would definitely repurchase

Neat and toasty

Yes, I recommend this

An excellent buy, strappy so that it doesn't show under buttoned or v or u neck winter tops and warm as toast as it is made of really warm thermal fabric, and it covers your bum too!! Lovely
