Amy Evans (Bristol, GB)
Really nice and good value

Size is great. They are very comfortable and firm enough to hold you in a bit but very comfortable and cone up quite high and don't roll down. Had many over fleece lined leggings that slip down constantly. Had these on all day and not had to adjust once. Going to purchase more

Lovely thermal leggins

Bought to wear under work trousers. They're not to thick to restrict me in any way but they are definitely warmer than a standard pair of leggings I was wearing for an extra layer. Delivery was super quick. I will use this company again


Great seller.
