"Such a gorgeous jacket! The fit is really flattering and gives a beautiful shape without feeling too tight. The fabric feels soft and high quality, and I love how easy it is to wear to the gym or casually. 🤍"
"My gf loves this zip jacket. It is very flattering. Such a clean beautiful look. Soft yet sculpting, perfect size. 10/10 recommend."
"Ordered this gorgeous jacket mainly for the colour and as soon as I slipped it on and zipped it up I had to go order it in black!! I love the way it hugs my body and makes me feel snug and compliments my shape so nicely ! I’ve brought a medium and it is a little ‘tight’ but I do prefer a nice snug fit."
"This jacket makes you feel so fit! Fits so well and material is so stretchy. Mine did come with a few stains on the sleeves but the customer support was fantastic and helped right away!"
"Love the fit and feel. I took the advice of others and sized up. This worked out well as it's still fitted and does up without being too tight. The fabric is great. Can wear with all my gym outfits throughout the cooler months."
"My favourite jacket to pair with almost any activewear its so slim fitting and hugs the waist"
