wildcorylus Heatgen™ Maximum Thermal Long Sleeve Top for men. Excellent product, very warm, fits well. I would like a bigger selection of colours though.

dinoindorset Best value Wash well and last a long time not the cheapest bit great value very warm for uk use

Tracy 01 Works Soft and warm, this is a second buy in a different colour. Washes up well and they really work. I am a lady size 12-14 i like the mens tops as they are longer in length plenty to tuck in.

Zamoyska Warm and smart My husband wears this as a top and it doesn’t look like a vest

KASKEW Maximum Thermal long sleeved top I bought these for myself after pinching my husbands. The best thermal for warmth on the market. I wish you would use the same material for woman. This one is for our cousin!

MaryHC Wasn’t Whst I Really Wanted I originally wanted to purchase the ladies maximum thermal, but it would seem they’ve been discontinued. I bought two last year and wanted some more. So I had to resort to buying the men’s version. They are warm, but too long in the body and sleeve. Why you would stop selling them for ladies I’ve no idea doesn’t make sense.

BENJAMIN30 BEST OUT THERE I’m an older tall women and bought these to keep,cosy, they are fantastic.

Free Palestine please warm It is comfortable and keeps me warm and is not itchy

AMD21 Mens Thermal Vest very soft and warm especially in this cold weather. My husband and son love theirs.

JA431 An excellent thermal vest A very warm, excellent vest. It fits perfectly, hugs the skin well, and makes all the difference between feeling cold or not throughout the winter.

Back to basics Wear well and wash well. I also Tumble them Purchased for Husband and Son to help combat the rising costs and lower temperatures. I have the ladies turtle neck version and have had them for a year. Fabulous for layering over the winter. They’re soft against the skin, we wear ours under shirts as the temperature drops then add the layers as it drops further. These are more stylish and warmer than the traditional thermal vests. My husband uses for work. Meaning he can have his top button open and this vest just looks like a TShirt.

Bessie65 Cosy feel and a good price My husband already had one of these thermal vests and was saying how lovely and warm it was and could do with another one. So I bought him one for Christmas. It’s so soft and a good price.

cosy cat Great buy Very cosy thermal bought for my husband who always feels cold !

German Warm but expensive thermal vest A lovely and warm thermal vest. My husband lukes it as the sleeves and body are nice and long.

Bon2 Thermal under top Perfect for keeping warm, though it’s longer than need be

Aethel Toasty Incredibly comfortable to wear and is a perfect base layer for those cold days.

Amelia86 A Bought these last year for husband and son and so pleased decided to buy more this year.

Nana_ Great It's so warm and great.It dries quite quickly after washing.I wear cotton underwear underneath this, but I don't think it makes my skin tingle that much. The S size sold out quickly at physical stores, so I bought it online. I was waiting for the same product for women to appear in physical stores, but it never appeared and was sold out online.

Ruffin Great Cold weather gesr Well made, comfortable and nice and long. Very warm

JH Hayle A soft winter warmer My husband loves his long sleeved top, so soft and warm, ideal as a winter base layer when working outdoors.
