These are amazing. Best leggings I’ve ever bought. True to size - I’m a size 12 and the 10-12 fit perfectly

I already have a top and track suit from thermal theory, the leggings are so incredible. I don't want to take them off, they are super comfy and warm. Highly recommend.
Btw - they run a bit small so size up

I went for an early morning walk today, it was 3 degrees. These tracksuit pants were excellent 👌🏿 perfect infact. Thank you.

Read so many excellent reviews about these and they live up to that high rating! I’m about 158cm tall and the regular leggings (opposed to the 7/8), fit well. I plan to wear them with long boots so I’m happy with the little extra coverage over ankle. They are thick and soft and super warm! Excellent customer service also prior to purchase (during my research stage).

I bought the original leggings a couple of years ago & the only downside was no pockets for phone or doggy bags while out walking, given that this winter seems to going to be extra cold I ordered ones pockets for walking, will use the previous pairs for work. Haven't worn them yet but if they are the same quality as the others I highly recommend. Nice & warm for a cold outdoors but can wear them inside without getting too warm.

Good quality, true fit and really warm!

My second pair of these super warm and stretchy leggings they’re amazing and with pockets too!

As we live in Tasmania, the winter weather can be brutal at times. This jumper fills all the requirements, is so warm and snuggly. Many thanks.

Seriously these are brilliant! I wear them walking, take my trainers off put leather boots on a jumper and a jacket and go out! Love them! Game changer- so warm!

Fantastic track pants. Great cut and made and of course super warm. Use the size guide for the perfect fit.

Not too thick, but very warm. True to size.

Love, love , love the clothing! So warm and comfortable!

These track pants are amazing! So warm and comfortable.
