For savvy shoppers, there's nothing quite as satisfying as finding a deal so good it feels illegal - and that's exactly what's happening on Amazon right now during Prime Day 2026.

Our editors are always keeping tabs on what's trending in celebrity street style, and A-listers always love activewear, but lately, stars are especially loving slim-fitted athletic jackets for the summer season. These dupes from Amazon nail the trend, but at a fraction of the price.

Celeb-Approved BBL Jacket: Yitty Ultraluxe Active Jacket

Best Overall Dupe: Magcomsen UPF 50+ Lightweight Athletic Jacket

Best Budget Pick: Aurvae Full Zip Lightweight Slim Fit Athletic Jacket

If you're not on social media, the term "BBL jacket" may be new in your vocabulary. The athleisure trend entails an athletic jacket with a slim-fit cut (creating a "BBL" hourglass effect), zip-up front and handy details like zippered pockets and thumb hole sleeves, crafted of lightweight, breathable fabrics that are ideal for summer. The outcome is a super sleek, streamlined look that can be worn to the gym or while running errands just as well.

Shoppers have been raving about these jackets for months now, so, at this point, there's plenty of options in a range of colors, sizes and styles to choose from.

Considering celebrities love an activewear look, here's our favorite picks from the celeb-approved trend, even Lizzo's brand Yitty has its own rendition – no one will know it was less than $30 on Amazon.
