Cosy and warm

Yes, I recommend this

Lovely thick thermal top that is lovely and soft. Bought for myself as I'm short (5'2", and usually M&S size 10), and it fits perfectly. Prefer this to the Women's version as this is much thicker and warmer and has a better neckline.

These tops are just right for the cold weather. Theyre thicker and warmer than the standard heatgen thermal tops. And good value for money. They wash well but cant be tumble dried so I hang them above a radiator.
