Good quality

These Thermals are quite good quality and are nice and warm on these cold winter days. True to size and very comfortable. The only slight complaint I have is I feel they are a bit too expensive for pensioners like me.

I'd already bought the Heatgen Maximum Thermal t-shirts for my husband and knew he was pleased with them so when he complained of having cold legs, decided to order these for him. They are the same great quality material (which includes merino wool) with a ribbed finish outside and a cosy brushed finish inside. My husband confirms that they're comfortable to wear and keep him warm. They wash well too.

Bought for my husband who was feeling the winter cold. I assumed they would be made from the same fabric as the ladies max Heatgen version, which are brilliant, but they are quite different. However, he assures me they are very warm, comfortable and a good fit, so one satisfied customer!

Along with the vest, I bought these as a base layer for playing golf in sub-zero temperatures. My first experience was in an ambient temperature of minus 4 and feeling minus 5. After 4 holes, I was so comfortable I had to take one of the top 4 layers off, so very impressed with their thermal capacity
