Good product for the price

These leggings are lovely and warm. The fabric isn't sports performance wear, but they don't claim to be. If you want thermal leggings for general wear in the colder months, at a great price, these do a job.

Great cosy leggings!

Yes, I recommend this

Love these leggings. Like the high waist and regular length is perfect for me at 5ft4. Usually size 8-10 & went for 10 which is v comfortable as didn’t want to feel too tight.

Good for autumn weather.

Yes, I recommend this

These leggings are thicker than normal, and feel like velvet on the inside due to having a pile. Ive only tried them indoors. Theyve been bought for dog walking during the cold weather as i suffer with cold legs. The fit is good. However, having only worn them once, i noticed the knees bag up by the end of the day.

Very cosy leggings. Just a bit unforgiving on the waist band

Soft, warm with a good length and fit

Yes, I recommend this

Very soft material and waist band. The length is good so my ankles are covered. I’m 5ft 6. True to size and no baggy crotch or knees. Would recommend.

For cooler days

Yes, I recommend this

Lovely super soft cosy fabric. Ideal for cooler days, either worn with jumpers or under dresses and skirts. They look great with boots or heels when you need something a little more dressy. The fit I feel is true to size. I’ve ended up purchasing all colours.
