The best activewear brands for 2025, according to our fashion editor
A large chunk of my 2024 was spent poring over the pages of the hottest gymwear brands on the market, testing and trying out pieces, chatting to experts, and keeping my nose to the ground when it comes to the best of the best.
So, if you, like me, are going into the new year with some serious fitness goals in mind (one of mine is to be able to hold a handstand for a minute...), you may be on the hunt for the latest and greatest of all things activewear.
From affordable and impactful global brands to smaller niche local labels breaking ground in new spaces, below are some of my top picks on where to shop and stock up before you hit the gym this new year.
So scroll on, get shopping, then get sweaty!
