Comfortable, warm leggingsVery pleased with my Thermodynamic Run Leggings. Although expensive they look and feel as if they will last a long time and have washed well so far. The most comfortable and warm leggings I've had - have even run faster in them! Only criticism is that, for my height (5' 8'') they could be a few cm longer in the leg, but they're longer than most other leggings.

Flattering leggingsI bought these leggings to play tennis outdoor in winter. They fit well and make your legs look longer. I wear them with the matching top and a glisten bamboo top or merino. The downsides are they are not quite warm enough for tennis on the colder days and because they are a slippery fabric the t shirt rides up so I have to tuck it in.

Best thermals by far!Bought these leggings as a must for this cold weather. The fleece lining inside is beautifully soft and the minimal design makes them a wardrobe essential.
These are my second pair of thermals by SB and I'm beyond ecstatic at the quality!
Well done SB, another pair of beautifully technical leggings to add to my ever growing collection!

Not good for runningThese leggings felt and looked great in the shop and are made of really lovely material, however they are impossible to run in - because of the weight of the fabric they just don't stay up and the crotch becomes lower and lower, resulting in you having to stop every 300m to hitch everything up and retie the waist band. Every time I try and run in these I get serious chafing which is pretty disappointing. I am a size 10-12 so medium SB leggings normally fit me perfectly. Annoyingly I only realised the issue once I had started running in the leggings at which point it was not possible to return them.

Just perfectI bought a pair of Thermodynamic run leggings in black last week in anticipation of the cold weather. I am 5 ft 11 and a size 14 I bought a medium size and regular length which fit perfectly. I wore them this morning when it was -1 outside and I felt as snug as a bug. The fabric does exactly what it says in the description it holds just the right amount of warmth while ensuring breathability when you sweat. The material is soft and warm and they look great, I actually look good in them! I feel great and fully prepared to embrace the cold spell which seems to be upon us! In my opinion these are worth every penny of the price tag.
