Great buy

Yes, I recommend this

Love this heatgen thermal vest. It’s so cosy and warm yet because it has shoe string straps it can be worn under dressy tops.

Quite like but a little long in the body for me

Yes, I recommend this

Thermal top the thin straps were a little long . However they didn’t slip down off my shoulders when wearing. The vest part was longer than I expected it to be perhaps not a bad thing because it more than covered my waist. The quality is good. I only gave it four stars because of the fit on me . It was more for someone with a longer body . I am more petite. Would suit someone a bit taller maybe over 5ft4in

Lovely and warm vest.

Yes, I recommend this

I usually buy a different brand but tried this in the cream. Surprisingly warm and very comfortable to wear. Maybe a little thick to wear under a thin jumper, but overall really pleased.

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.
