More fashion than function

I think the style is cute, but the material is so thin it makes it seem kind of cheap/not quality. Plus, there’s no way you could wear this outside of summer outside or spring for a run. No good for winter. I preferred the quality of material from previous two windbreakers from SB. Sadly this one is going back.

I really like this run jacket as it is very soft and fit my figure very well. Just what i need for this winter time and the balloon sleeve is fab. I highly recommend this product.

Super stylish with some personality

Unusual and creative cut - especially fantastic if you have broader shoulders. Not as flattering on the body as it probably could be for a size 12/14/larger bust, but lovely worn undone, for sport, or casual wear.

This is the first time I have felt stylish on my run! I love the big sleeves with the super cosy snug fit body. Its not my usual style but Im really glad I gave it a go, its so flattering but also really warm. I bought my usual size S and it fits perfectly #teamsweatybetty

The most stylish run gear ever!

I have to admit I wasn't sure as this isnt my usual style, but Im so glad I went for it! The oversized sleeves and fitted body are so flattering, and I feel like Im on the catwalk not the school run. Definitely different to my other running jackets, but I think I'll get more wear out of it because its nice enough to wear even when not exercising. #teamsweatybetty
