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.

Perfect warm top

Yes, I recommend this

I bought this to wear as a warm t shirt under v necked tops . It’s perfect . It fits well and is warm and soft but not too warm. I wish I could get nightwear in this fabric it’s so comfortable. It’s definite a top not a vest which is why it’s so nice to wear.

Variable fit

Nice and soft. Warm. The grey one was fine. The cream one was too tight at the neck.

Soft, stretchy and long.

Yes, I recommend this

Very soft and comfy. Not sweaty. True to size but it's very stretchy so it would be fairly flexible, size-wise. Nice and long so it stays tucked in to skirts or jeans. And no annoying scratchy label on the neck!
