Disappointed

No, I don't recommend this

Good quality but much thinner than I was expecting. Having worn Heatgen tops for many years, I thought my husband would benefit from their warmth. So disappointed that they were a very fine knit.

Having had the Heatgen Light Thermal vest for the first time, I found them to be excellent in keeping me warm in the inclement weather we are experiencing. Almost like a mini radiator under the outer clothing!!
