These thoughts I love the feel but the quality isn’t the same as 3 years ago I put my thumb through them on the first wear which really disappointed as I had my Previous pair for over 3-4 years and they are as good as new you also have to order theses they are not out on the shop floor again disappointed

Love these tights - have them in grey and black. So soft and not a shiny finish which I prefer.

Lovely and soft material

Originally posted on marksandspencer.com (UK)

I have not worn these yet but they feel really soft, thick enough for full cover, nice and stretchy. I would say true to size, I am 5ft 5 ins and bought medium. Looking forward to wearing them.

I always wear M&S thermal tights but have never tried the 100 denier . They were very warm and I was happy with the look of them able to wear a skirt in very low temperatures on holiday .. intend to wear on cold days at home !

Bought these Tights to wear under trousers whilst visiting Kaunas, they were very comfy and added that extra layer needed in sub zero temperatures without being too thick.

These tight are great

These tight are great - they are light weight, yet cosy - wearing them they appear to be good quality 40 denier tight, but have the hidden depth of being thermal that keep you legs warm!
