Don't think just BUY

This is one item you don't need to think about first. Just buy it els you will be disappointed not getting it.
I feel so **** & confident in this top. I have very broad shoulders & back & on top of that I have a decent amount of muscle, I battle to find a fitted long sleeve that fit perfect for my build. Then I try this top on & instantly feel inlove, for the first time I hVe found active wear that fits my build so well. BURNT! please make more colours of these tops they are so perfect.
Oh also the watch slit : GENIUS! & still comfortable even if you don't wear a watch also not noticeable of the slit if you don't wear a watch

Absolutely in Love!

The Onset Technical 1/4 Zip Up from Burnt Fit Studios is fantastic! This zip-up is a game-changer for my workouts. It keeps me warm during early morning runs, but it’s breathable enough to wear for indoor sessions too. The material is top-notch, and the fit is just right – not too tight, not too loose. Plus, the design is stylish and modern. I’m extremely satisfied with my purchase! 🧡
