While testing sports bras for last year’s SELF Certified Awards, I came across a few high-impact sports bra options I liked, but fell completely in love with the Runderwear Easy-On Support Running Bra, which may easily be the most streamlined, well-fitting sports bra to ever grace my big bust during a workout.
Runderwear is based in the U.K., like another of my go-to bra brands, and designs apparel and base layers specifically for running. According to fitness experts, a good high-impact sports bra should have a snug fit and full cleavage coverage so your breasts don’t move around, and this one checks all the boxes. While I’m a fan of wearing this sports bra during outdoor runs or while on the treadmill, it’s versatile enough to handle any high-intensity activity, from The Class to HIIT.
Unlike shapeless, frumpy sports bras I’ve owned that make me feel like I’m wearing something from my grandmother’s closet, this bra is actually cute enough to wear without a top. It shows a hint of cleavage, which I love, but never makes me feel nervous about anything accidentally popping out during my toughest workouts. The bra features a set of sturdy molded cups that don’t leave me with the dreaded uni-boob, and has an over-the-head design that’s easy to pull on, with adjustable straps for a custom fit. The back of the bra has two hook and eye closures—like a regular bra—that open completely (making it simple to take off, too, even after a sticky workout).
As someone with a big bust, I especially appreciate how the Easy-On bra has size options ranging from A to J—which is way more inclusive than a lot of bras I’ve worn (read: stuffed the twins into). Despite being surprisingly slender, the bra’s padded, contoured straps are comfy to wear and fully support my bust (no small feat). The material is breathable and soft, wicking moisture beautifully, which I definitely need during my sweatiest exercise. And since this wonder bra is totally wireless(!) with a smooth, wide underband, I don’t have to deal with a pesky underwire digging into my ribcage.
After wearing this Runderwear sports bra just once, I was so impressed that it quickly become one of my tried-and-true favorites, managing to keep everything in place through burpees, jumping jacks, and more without missing a beat.
