Nice but fairly lightweight.

Nice enough to wear as a T Shirt as well as base layer depending on colour. I ordered a cream & a grey marl. The cream one was rather thin & see through, whereas the grey marl felt better quality??

A lovely slightly lighter weight t shirt than the maximum Heatgen. Wears & washes well & still lovely & warm to wear. The fit & fabric are excellent

Lovely warm top.

Yes, I recommend this

Really warm and cosy without being bulky under clothing. Quite a tight fit across the chest. I prefer a looser fit for comfort so bought the next size up.

Great Quality

Yes, I recommend this

This was brought for a specific winter holiday to Austria in December and it does keep you warm in colder environments. It is also a good fit and the material is of good quality.

Warm and flattering

Yes, I recommend this

Really good fit, although I did go a size bigger in order to feel looser over trousers. I wanted something to wear for regular hospital visits when I need to keep my arms bare but my body warm. It certainly works for that but it also delivers under shirts, cardigans and other layers. Lovely feel to the fabric.

Fairly warm

No, I don't recommend this

I decided to try some alternatives to my expensive Merino wool vests. This is fairly warm, but it falls short of the Merino wool, so I am going back to that. It is more expensive, but it is also warmer than these alternatives.

Medium Short Sleeve Thermal Top

Yes, I recommend this

Warm, really comfortable and not too hot. Love It. Goes well with the leggings that I also bought. Love the flexibility of being able to buy Heatgen Maximum for leggings and Heatgen Medium for the thermal top which really suits my body temperature range.
