Seems fine for now

Originally posted on sweatybetty.com

Bought these for walking and playing tennis in winter. Not worn it out yet but definitely feels the fleece lining. Washed okay too. Hope it keeps me warm. Got my usual size S and the waist and ankle are a bit tighter than the power leggings and super soft leggings.

Warmer leggings so good for colder days. Not at all heavy. Useful side pockets.

Cosy and a good fit.

I bought these leggings for coming into the colder weather. I haven’t therefore tried them yet but the fit is good and they are cosy. I was surprised when the came that they seemed a lot smaller than my other XS Sweaty Betty leggings both at the waist (about an inch smaller) and in the length of the leg (about 2 inches shorter) but they did actually fit when I tried them - material must be more stretchy.

Overall good running legs for cooler weather

Originally posted on sweatybetty.com

Yes, I recommend this

I had a pair of "thermodynamic" running legs from a few years ago and wanted another pair. These are good quality but not as thick as my previous pair. Having said that, they are still warm, look good, fit well, feel soft and I don't mind the stitching on the reflective tape. I bought them in the sale and so I feel they are value for money, although I have yet to test them on a winter run!

The best leggings I have worn

Originally posted on sweatybetty.com

Yes, I recommend this

I use these leggings mainly for running, but also for gym sessions and cycling. They are comfortable, do not slip down and have well placed pockets. I like the extra thickness of the Therma style. They wash well and last a long time. My go to legging.

These feel great! Did a track session in them where you stand around a bit but they kept my muscles warm in between runs.

I bought these as warm leggings for walking in. Tested them.on a windy walk and they were perfect. Lovely and soft to wear and kept me warm in the wind. Decided to size up from my usual size to give day long comfort while walking and I was pleased I did.

Love these leggings for their material, nice and warm. But had to return as they were too tight compared with other styles in the same size.

Originally posted on sweatybetty.com

For outdoor in all weather kettle bells/boot camp style training these are fab, winter runs or just walking the dog…. I have lived in mine all winter so thought I should treat myself to a second pair. Will be getting out my power leggings for the spring though….

ideal for long legs

Originally posted on sweatybetty.com

Yes, I recommend this

I have an inside leg measurement of 36" - these leggings are more than long enough. The fit is excellent and they were warm for a long springtime hill walk. The pockets are wide enough to get your whole phone in - no popping out or crammed into little zip pockets. And i was fortunate enough to buy them in the sale - bonus.

Definitely warmer than the normal leggings for winter - great for yoga as the studio can be a little chilly at this time of year

Really comfy but not very warm

Originally posted on sweatybetty.com

Love these for an outside run, but they are not that warm, so you'll definitely want some plus degrees outside. Very nice feel though, I find myself wearing them around the house, too.

Thermal Leggings

Originally posted on sweatybetty.com

Yes, I recommend this

I bought the thermal boost leggings as an addition to my ever growing Sweaty Betty collection but wasn’t disappointed . Got them half price in the recent promotion . They are a lovely thick material with a brushed fleece inside , not too warm for walking in cold weather we’ve had the last week . Two side pockets and a back zipped pocket is great . Size same as other leggings I’ve bought too . Would recommend over other cheaper thermal leggings I’ve had , good investment for winter .

Love these thermal leggings for walking, cycling and running in winter, warm without being too fleecy and sweaty which I’ve found previously with some thermal items.

Not very impressed as this happened on day one. It’s literally easier to spot a unicorn than get hold of anyone from customer services! Still waiting for response to messages. Hopefully this might prompt it!
