Very thin

No, I don't recommend this

I’m not sure these are any better than normal black vests. They do the job as a vest but no thermal extra as far as I could tell. Very very thin. Next time I’d just buy basic.

Warm vests

Yes, I recommend this

I've bought them to wear under long sleeved tops and fleeces to keep me warm when I'm walking the dog! They are exactly as described, stretchy and straps that can be altered. I'm normally a size 14 but bought size 12 and they fit perfectly!

Fantastic vest. Really good fit with the adjustable straps. Not bulky but warm. Very nice feel on skin. Why can't i get them in more colours?

Not disappointed

Yes, I recommend this

These are just what you need when the sun starts to shine but it's not exactly warm yet. Good quality, lovely soft fabric.

My new favourites

Yes, I recommend this

These turned out to be exactly what I wanted, comfy fitting vests with adjustable straps - if only you could also stock white and other colours too…

Lovely soft thermal vests. Definitely kept my daughter warm and very comfortable to wear. Good value for money and wash very nicely. Would recommend and buy again. True to size.

Lightweight Extra Layer

Yes, I recommend this

Bought to replace ones I had years ago. Prefer the lightweight heatgen as not too bulky under clothes. Adjustable straps, 14 ideal size fitted for 36f bra size. Soft material, only wish I could have them in white, as I had to buy the medium warmth in white on line, and it’s rather thick fabric also the straps are not adjustable . Keeping thermals for the British heatwave.

Disappointed. Get one single

No, I don't recommend this

V thin. They are than the single one I had bought although the product content weirdly is exactly exactly the same. Really annoying.

To short

No, I don't recommend this

Nice fabric true to size but too short to stay tucked in. So you end up with a chilly gap.

Ok

No, I don't recommend this

The last ones I bought had a warmer lining. These are just cotton camis. A tiny bit short, I think.
