I am a huge fan of the M&S long-sleeved thermal tops. The very warm ones that have a sort of fleecy layer inside. They are warmer and softer than anything else I've tried.
My DP would like something similar but M&S thermal tops for men are very different and nowhere as warm. We did try getting a larger size in the women's range for DP but the neckline doesn't work.
Can anyone recommend some very warm thermal tops for men? Something that, ideally, is slightly fleecy on the inside? No (merino) wool please. Thank you.
