Strange fabric

No, I don't recommend this

Unable to view this in store so I purchased online. Firstly, the fabric feels very unpleasant. It's very synthetic. However, inside feels nice and soft and that's good because it's on your skin. However, I think if I had felt it in store then I wouldn't have purchased. It feels very different from the lightweight Heatgen thermal printed tops. I do like the leopard print pattern and it does keep you warm because it is thicker. It has a good stretch, so if you do go indoors and get warm then you are at least able to push the sleeves up.

Lovely top

Yes, I recommend this

Lovely top. Had to size up for comfort though. Wouldn’t say I’ve found it particularly warm but it would be perfect for layering.

Great warm top!

Yes, I recommend this

I love the colour of this top. It’s a little thicker than I initially thought as I have other heat gen tops which are fabulous for layering. This will be also it’s just a bit thicker but could be worn on its own under a tank top or sleeveless dress etc and still be warm. The sleeves are a little long as I prefer to push mine up but there are gathers at the top of the arm which I’m not keen on but that’s perhaps my build.

Comfortable

Lovely comfortable top. Chose a bigger size than normal and it’s still a bit snug. Good enough to wear just as a top and not under anything.

Tight neckline

No, I don't recommend this

I found the neckline on this thermal top is cut too high. Irritated my neck immediately when i tried it on. Otherwise fit true to size. Will return for a refund

Great quality

Yes, I recommend this

This is a lovely warm and cosy thermal top, it is snug fit , which is the idea I guess, to keep warmth in, but if you prefer a looser fit I would recommend a size up. I think I will be buying another in black as I’m so happy with it!

Cosy top

Yes, I recommend this

Just started wearing this as the weather has cooled. Very impressed with the cosy fleecy lining. It is thicker than I expected so can be used as a layer or as a top on its own.

Yes, I recommend this

Every year I add to my Heatgen Collection of thermal tops. I have a core collection of plain colours and now try and add a patterned long sleeve top to the existing portfolio

Lovely top

I love leopard print! Very stylish as an extra visible layer. It would be even better if this was in maximum warmth.

Thermal wear with absolute Style!

Yes, I recommend this

Love this garment. Just the right thickness to wear under blouse / jersey and on the plus side to wear independently as a top. Received compliments…. Bought a 2nd one sizing up from my 1st one (usual size) the 2nd to have a slightly longer length to see under jerseys. So love this - highly recommend!

Really nice print for a thermal

Yes, I recommend this

Bought this ready for the colder weather. Really nice print , can wear this just as a top no need to hide it, but also easy to layer. Feels lovely, thick and warm looking plus a nice length. I always size up in thermals as I think they tend to be really quite tight. This feels snug to keep the warmth in but not too tight. Not cold enough to test it out yet but I’m sure it will do the job.

So cosy!

Yes, I recommend this

This is very warm and snuggly, with what feels like a brushed inside. The neck seems to sit better than some previous thermals and because it’s leopard print it can peep out of the neckline of what I’m wearing without looking too much like underwear.
