Very cosy top

Yes, I recommend this

Lovely warm top, very comfortable, nice soft fabric, useful crew neck - not too low and not too high. I wish there were more colours available. I went up a size as I found it slightly narrow.

Perfect Layering Item

Yes, I recommend this

I purchased a couple of these tops after seeing the weather forecast for very cold weather incoming. They’ve been invaluable in the cold snap for layering under dresses or jumpers. Aesthetically they’re pleasing as they’re figure hugging and not bulky at all. They’re nice and long covering my belly and wrists and were excellent for keeping my core warm. They’ve washed a treat too. I’ll continue to wear these on their own as long sleeve t-shirts as they hold their shape much better than normal long sleeve T’s

Wonderfully warm

Lovely warm thermal T shirt top. But fit a bit odd, crew neck is so high in the front it rides up my neck, needs to have alt toe more depth at the front neck

Perfect for colder weather

Yes, I recommend this

I bought 3 of these heatgen tops to wear under jumpers etc in the colder weather. I’ve been wearing them on rotation every day now. They are quite a snug fit, I purchased M but I think that’s how they are supposed to be, to retain the warmth.

Excellent winter tops against the chill!

Yes, I recommend this

I love these Medium Thermal Crew Neck Tops. A crew neck is ideal for winter months, I’m so pleased with this style. They fit well, are comfortable, warm and cosy. I have a few of these, and getting another for Christmas! I have recommended Heatgen tops to others.
