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.
