Therma Boost 2.0 Printed Reflective Leggings

Warm and soft leggings , nice pattern , charcoal grey colour

Easy to order online and quick delivery. Products are always great quality. These therma boost leggings are the third pair I’ve puchased and I love them. I’m 6’1 tall with a 36inch inside leg. The full length legging is about an inch and a half short for me, however as long as I wear a longer pair of socks I can make it work. They are very comfortable to run in, certainly keep me warm on those longer runs and are very soft. They wash incredibly well and I love the reflective strips and patterns. Great for those dark morning and evening runs and that transition at dawn and dusk. Will buy again for sure!

Really soft warm leggings. I have been running in regular leggings and really noticed the difference with these thermal ones, but equally they didn’t feel bulky or too hot. I have not had sweaty betty leggings before but I have had the gary yoga pants which I wear in an XS. I sized up to a S in the thermal leggings as some reviews say they are a slightly snug. The S is fine - not bug but not too tight either - but I think the XS would have been ok too. I got regular length and the length is fine on me but if you are taller than maybe 5 7” they might come up a little cropped. For reference I’m 5 6” and a uk size 10 in most brands (US 6 in lulu lemon, a small in adanola if that’s helpful)

They keep you warm without you getting overheated. They’re not noticeably thicker than standard leggings. They are expensive for a pair of leggings but they are built to last and are very good at what they promise to do. I’m tight but I wholeheartedly believe they are worth the money. Recommend 100%

I bought these thermal tights for warmth during winter and for being reflective when out in winter’s long, dark days. The tights seem warm enough but the reflective patterning is more dull than the images online show. I thought these tights would have more contrast.but instead look dull. Fit is true to size.

Super soft and comfy and it doesn’t take Olympic skills to get them on and off!! So happy with them in fact , bought a pair for my daughter, too!!

These leggings are the best winter running leggings ever! They’ve kept me warm during some really frigid night runs (-5C). I won’t wear anything else. I have 2 and hoping a navy will be released. I think they’re TTS - I got the same size I wear in my power leggings. These are not nearly as stretchy as the power leggings but I think they’re tts. As a tall girl (173cm) I could use about an inch more length.

These leggings are warm and highly reflective, and I like the 2 side pockets, but the fit is a bit too snug and for the first time (I have a lot of SB leggings!) I can feel a distinct band of elastic round the waist. So they’re good for winter pursuits but they’re not my favourites.

Very disappointed with these leggings I’m going to take them into my nearest M&S store I have several pairs of Swetty Betty leggings including 3 different pairs of thermal ones all of which I’ve been extremely pleased with. But these were thin ,how they could be called thermal is a joke . The fit was not good and the pattern was horrible. £100 ridiculous 😩

Really like these tights for colder weather. They’re warm without being heavy or bulky. Fit is similar to other Sweaty Betty tights Haven’t tried them at night, but I would expect they are very reflective.

I was worried they'd be too small. I'm a small 14 and bought a medium but they fit like a glove and don't slip down - hurray! They're warm even in Scotland. So happy with them.

Lovely fabric, soft and warm on you the inside. The length is perfect. I did size up for the waist. My more recent purchases of leggings these and power are much tighter at the waist. My older leggings are more generous at the waist. ! Warm for yoga in a cold village hall.

Soft, thin fleecy inner lining which does not limit movement. It is still a little thin for the zero/subzero degree days in London but otherwise does the job on an average winter day.

Fabulous but too short! They are so comfy and warm to wear when I run in them. Perfect for these winter nights. Unfortunately they are much shorter in the leg than my other power leggings so I end up with a gap between my socks. I’m 5ft 8 and bought the full length and have never had this with a pair of powers before, hence the reason for not giving 5 stars. Apart from that they are totally perfect!
