PerfectThese are my 1st SB purchase, after deliberating what leggings to go for after weeks of researching, I settled for the thermodynamic and i'm thrilled I did. These are perfect, I don't want to wear anything else!
I go to an evening outdoor Bootcamp a couple of times a week as well as an odd run here and there, recently the temperature has dropped to -4 degrees c and these kept my legs warm and comfortable.
They don't fall down (all other leggings do on me! I must be an odd shape!?!) which is such a relief!
I'm a UK size 6-8, 5'4" and went for XS/short to help anyone a similar size unsure what to go for.
I can't comment on how well they survive washing as they've only been through the machine once, fingers crossed they last me years. Thank you SB, I can't believe its taken me so long to purchase from you! Saving up for my next item!

Amazing!These have to be the best SB run leggings I have ever owned (and I have a few) including a thermal pair that have been my staple winter running wear for a few years.
So when I spotted these I couldn't resist giving them a try and I'm so glad I did.
The fit is perfect, I've always been a small in SB leggings and these are true to size, and once on they stay put.
Really comfortable, snug and warm, but not so warm that you overheat while on longer runs.
The pattern is a bonus, as nearing 50 I don't like active wear that is too bold, so the block colours on one leg are subtle enough not to make them boring.
If you are looking for winter running leggings I can't recommend these enough.

Perfect thermal leggingsThese are my second pair of SB thermal leggings and they are so comfortable and warm. Perfect on icy runs or popping to the shops. The only issue I have found is the orange colour block detail on one leg has darkened after about 3 washes... I love bright colours and it looks a bit muddy against my orange compound vest. Otherwise, fab.

SnuglyI run a series of outdoor exercise classes and these have been my saviour ... really soft and fleecy on the inside, they keep me nice and warm whether I'm running or standing around ... Either way ... I never get too hot. I bought the short leg (I usually buy the regular leg) as I felt they came up a fraction long (I"m 5'5'' with 32" legs)
