    Rated 4 out of 5 by from Very Comfortable These are incredibly comfortable and flattering... I love the shot of blue. The only point of note is the blue lines that go from the waist to the thighs are cracking already...

    Rated 5 out of 5 by from Perfect temperature regulating leggings These leggings are perfect for cooler weather. Trail running in the Dales usually brings changeable weather. These leggings provide lots of warmth without making me too hot. They feel luxuriously soft and the back pocket fits a phone easily. The fact that they are super flattering is a bonus. I have the blue ones, they don’t reflect like the black ones but do reflect a little.

    Rated 4 out of 5 by from Warm, comfy, thermodynamic run leggins. Good fit Good fabric Feels like a good fit on the waist Not too low and not too high on the waist. On previous leggins many feel too low on the waist. Also i find the mesh panels in many leggins to irritate my skin. Ive also heard the same in stores from other customers when ive chatted generally, who agree. And the store assistants said they have many people say they have issues with the mesh. I also felt dissapointed with the reversable leggins (capri), last year, as the black side ended up with the lighter seams from the other side showing through after a few months. As they couldnt locate my receipt, i was unable to change them.

    Rated 5 out of 5 by from Comfortable, warm leggings Very 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.

    Rated 4 out of 5 by from Flattering leggings I 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.

    Rated 5 out of 5 by from 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!

    Rated 1 out of 5 by from Not good for running These 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.
