Disappointed....

No, I don't recommend this

The sizing is NOT the same as the other Thermal items or even the standard short sleeve vests. Purchased the same medium size and they are somewhat 'snug/tight' fitting.

Bought as gifts as I was impressed with my own purchase over a year ago. They are lightweight, easily worn under other clothing quick to dry when washed, don’t loose their shape and lovely and warm.

Excellent quality and comfort

Yes, I recommend this

The M&S 2 Pack Light Heatgen Thermal Inners are excellent quality and exceptionally comfortable. The fabric feels very soft and smooth against the skin, making them ideal for all-day wear. They are lightweight yet provide effective warmth, without feeling bulky. I find them perfect as an underlayer — I wear them to work under my shirt, and they also work just as well under hoodies for more casual wear. They sit well, don’t restrict movement, and maintain their shape throughout the day. Overall, a reliable and well-made product that delivers both comfort and performance.
