Great running top

Great running top. Love the length and the reflective strips. This running top is a good length on me and the arms are a good length. Really pleased with it and feel it will be the first of many.

Cosy and fitted.

Bought this to go with the matching Thermaboost leggings, and to make sure i’m visible on the dark mornings. Lovely and soft, cosy enough to help me cope with the minus temperatures!

Good for spring or autumn morning runs

Originally posted on sweatybetty.com

I purchased the reflective version in the sale. It fits nicely, and is cosy and soft. I would have preferred it to be slightly thicker for winter morning runs, but I'll wear a base layer underneath it. It's probably better for shoulder seasons rather than winter! Good value in the sale but I would not have kept it if I paid full price.

Funnel neck sweatshirt

Yes, I recommend this

I ordered a size 12 in this top, because they hadn’t got a size 10, to be honest I like the fit. I do not like clothes too tight. The arms are a tiny bit long, but I suffer with that problem occasionally. It is well made and comfortable. Love the design. Would recommend.

Be safe, be seen! And it’s soooo comfy!

Always so easy to order online! My bank account might suggest too easy… That said Sweaty Betty never disappoints. Their range of sportswear are top quality. This therma boost running jacket is the first I’ve invested in and there will be more being added to the collection for certain! I’m 6’1 tall with a long wing span and I struggle to find running clothes that fit me well and are long enough in the sleeves. I have no worries in this department with the SB brand though. The sleeves are long enough that I can even make use of the thumb holes. I cant tell you what a treat that is for me! Super comfortable to run in, fits well and I feel good in it! It also keeps me nice and warm. Lovely and soft with a light fleece lining and it washes incredibly well. The reflective and pattern means I am seen so it’s great for being out in the dark and on those dusky mornings and evenings.

Great outfit disappointed in delivery

Originally posted on sweatybetty.com

Yes, I recommend this

Elegant and functional running gear. I feel great wearing it and keeps me warm, but also seems to regulate temperature when running hard. I bought with the leggings so very expensive which should have meant express delivery but I waited over a week. This is disappointing for SB so star removed.

Pockets!

Originally posted on sweatybetty.com

Yes, I recommend this

Stood up well to some ghastly November weather, somehow manages to be both light and warm at the same time, and no fear of not being seen with the reflective dots. Between this and the matching leggings I had so many pockets I didn’t know what to do with them!

Not the same quality

Originally posted on sweatybetty.com

No, I don't recommend this

I love my therma boost running jackets from previous years (retro green, hour blue) but this was no where near the same quality. The fabric felt thinner, the jacket no longer has the handy back pockets and the mitten feature at the cuffs was smaller than previous years so wouldn't fit me properly. I was so disappointed because a fully reflective thermal set would've been perfect for cycling and running in winter. Sadly had to return.

Nice colour but too thin

I was really looking forward to trying them, but for my liking the fabric was just too thin and felt too shear.

Great Winter Running Zip Through

Originally posted on sweatybetty.com

Such a great winter running zip through, the improved fabric feels so great and cosy against your skin. The fit is amazing, not too tight and makes me look very streamline! overall 5* from me SB! #teamsweatybetty
