Lovely and soft material

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!

Great winter tights

Lovely colours (bought navy and grey), great fit and long enough for my 32” legs! True to size. The waist comes up high enough to stay in place but too high.

These are nice tights but the thickness is not providing a lot of warmth I would have got thicker texture tights if I'd known.

Soft, Flexible and Warm

Originally posted on marksandspencer.com (UK)

Great price point I went for XLGE - these are soft, thick and flexible and very warm. The material feels natural and not man made. These are brown coloured and I wore it with a navy cord dress and platform chestnut coloured boots. I would definitely invest in another couple of pairs, great quality M&S baseline product.

I bought these several years ago and needed new ones. Big mistake buying two pairs. Quality really has gone on these. Elastane is gone and tights dropping down while walking.
