Warm and very cosy

Yes, I recommend this

I had already purchased a Heatgen Maximum Thermal garment for my husband and he had found it to be really comfy to wear, so it was the obvious choice to buy another for him. He needed something warm and cosy to wear beneath his jumpers and this ticked every box. Warm and snug with its soft fleecy inner next to his skin, nice long length, which is great for keeping his back warm, long enough to tuck in, no gaps around his waist if he stretched up, like with some underwear. It's a lovely fit, good enough to wear on its own especially with the winter's cold weather still with us. He could quite happily wear it on its own. Really pleased with it. Washes well, and looks great.
