Warm, comfy leggings

Yes, I recommend this

Just the right level of warmth for me, great as an alternative to tights in winter (and waistband is much comfier than the thermal tights I tried)

Warm and cosy!

Yes, I recommend this

Warm, cosy, great fit (although would recommend sizing up if in between sizes). Nice and high on the waistline so covers bottom of the back. Thin enough to wear under most things. I wear under scrubs at work but also under leggings at home

Winter essential

Yes, I recommend this

I absolutely love these thermal brushed leggings for winter, I wear them under skirts, joggers, abayas and trousers on extremely cold days. They keep me snug, warm and comfortable while out and about. I highly recommend them to family and friends. My daughter loves them too.

Superb product

Yes, I recommend this

This is one of the products M&S have got just right. I own quite a few of these in different thicknesses, I have suggested to the design team to produce them in different colours as I'm sure people would wear them in the spring and summer. Great garment, well designed and so far so good.

Gorgeous leggings - keep you lovely and warm in the water months - I wear them every day. On the very coldest days I switch to the maximum thermal pants. Wash beautifully.

Purchased many times

Yes, I recommend this

Nice and warm. I purchased a size up as i didn't want them to be stretched to much as i find thats when they become more see through and not so warm. Purchased size 12 and i'm normally a 10 can be a12 depending on where i shop. I have purchased these many times and not been dissappointed. The material seems to be a little shiny this time round though. Love the fact they are actually leggings as a lot of thermal leggings have gussets in them which means they have to be worn with long long jumpers/tops or dresses.
