Great fit & warmth for running

This is my second pair of thermal tights & they are perfect for me. I do like that there are deep pockets on both hips. It’s warm and a flattering fit. I’m 5’8 & 114 lbs. size S

So soft and comfortable

So soft and comfortable. Not sure they will be as thick and warm as my previous thermal leggings. Double deep pockets are fab

Comfortable & Perfect fit.

I bought these leggings for walking and work out in an unheated gym. They are very comfortable to wear and I love the colour. Only give four stars as I feel the quality of Sweaty Betty clothing has decreased.

Toasty warm

I bought these for running in the chilly surroundings of the Peak District in the UK. I was finding myself with cold legs and tummy when running in winter and these were recommended to me. The fit is excellent (I got medium and am a 10-12 with wider hips) - they are nicely high waisted and supportive without digging in. I got 7/8 length as I am only 164cm tall so they do leave my ankles a little exposed to the mud of the trails! The phone pocket is high on the leg so is comfortable to run in and most importantly the lining is soft and very warm. I got them with discount but I would be happy to pay full price for another pair as they seem so good.

Cold ankles

I have short legs so usually go for the 7/8 as a full length, but these are short for full length, they come almost as high as mid calf, which is weird for leggings that you want to be warm. They are nice, but not the Thermodynamics. I wish those would come back.

Therma boost leggings

Soft, comfortable and warm just what i wanted. 5ft 4 so ordered the 3/4 length and just above my ankle bone. Will be wearing with boots so perfect. Lovely shade of green.

Therma Boost - Size up

Lovely colour and quality. I was expecting them to be slightly warmer but still a good legging. I followed the sizing recommendation and found they fit small so would recommend sizing up.
