First time thermal vest wearer - I’m converted!

Yes, I recommend this

The thermal vest is amazing - not sure how it makes you feel warmer as soon as you put it on, but it does. Adding this extra layer when sat at home and I’ve been able to reduce my heating a bit. Outside it definitely works in the colder weather. And easy to wash

Another winter

Yes, I recommend this

I have many of these thermal vests and I find them comfortable and hard wearing. They keep me warm and fit well. The only thing that would make them 5 star is that the sleeves could be longer.
