Lovely, warm vest

I’ve bought several of these. They’re really warm, even though they’re strappy style. They wash well and keep their shape.

Beautifully soft and warm

Yes, I recommend this

This is so soft and warm and a really good length so it can be tucked in without the worry of it coming out. I didn't want to take it off at the end of the day.

Great quality item, does exactly what it says!

Yes, I recommend this

Superbly soft and warm, excellent for chilly days under a blouse or sweater. The camisole style is feminine without sacrificing the benefits of the warm extra layer they provide. Bought all the colours and very pleased with the quality.
