By now, you'll know that Team Marie Claire UK think Kate Middleton has a pretty flawless sense of style. Sure, she might have a team on hand to help her serve consistently stylish looks, but the Duchess of Cambridge always looks amazing - even in workout gear. 

She's known to be a fan of brands including lululemon, New Balance, Veja and Nike, but one particular item that both the Queen-to-be and MC UK Senior Health Editor Ally Head love and wear on repeat is lululemon's best-selling Define jacket.

Kate was last seen in it on a Royal engagement at the City of Derry Rugby Football Club field in September of 2021. While on a tour of Ireland with Prince William, she attended the club, trying her hand at some of the throws and chatting to locals.

You're reading this now because the lululemon Black Friday offering is one of the brand's best to date, with as much as 60% off their best-selling items. Of course, when we saw that the Duchess' favourite lululemon Define jacket was at its most affordable price ever, we had to share the news...

For the occasion, as usual, the Duchess kept her look simple, opting for the jacket in black and pairing with black trousers, to boot. 

The zip-through style is made from the brand's signature cotton soft Luon™ fabric and has one of their most flattering cuts, a zip front, high neck, not to mention thumbholes to make sure your hands stay warm and the sleeves stay in place. 

Kate also paired hers with a pair of New Balance x Sweaty Betty 'Vazee' trainers, which are £80 off this weekend only. She's also been spotted more recently wearing lululemon's Chargefeel trainers, currently half price.

As a Health Editor, I wear this jacket on repeat. It's easy to throw on, super flattering, and sweat-wicks well, too, meaning you can wear it for running or weights or to keep you warm on your way to Pilates. It's also a stylish option for brunch or weekend walks. 

While the Define jacket is designed with adventure in mind, it's also great for dog walking, brunch, and running errands, too, thanks to the label's signature butter-soft fabric.

It's one of their best-selling designs for a reason, available in the UK in sizes 4 to 24.

Other need-to-knows: it has zippered pockets, including a hidden pocket for your cards making it practical yet fashion-forward. Things we love to see!

Of course, it wouldn't be a gym kit recommendation from Marie Claire UK if it didn't perform well and look good, too - we test everything over a number of workout styles before we recommend you buy it so you don't end up wasting your money on things you don't need. 

This Editor and Royalty-approved jacket gets our seal of approval. It's breathable, sweat-wicking, supportive and stretchy - but not so stretchy that it'll lose its shape in the wash.

Trust me - I've had mine for around five years now and it still looks and feels the same as the day I bought it, despite getting some pretty serious usage over the years.

While Black Friday can be a great opportunity to invest in pieces you've wanted for a while at a more affordable price point, do make sure to think twice before opting for any impulse buys that you might not use. That said, if you're on the fence, kit from lululemon always gets our vote as it's genuinely built to last and performs well.
