<p>Whether you have large or small breasts, choosing the right style can make <a href=” exercising</a> more comfortable. Generally, the bigger your <a href=” size</a>, the more compression you need, which is a hugging sensation to prevent movement. Before dropping your hard-earned dollars, our experts spelled out what kind of support, sizing, and materials are important when finding your best fit. </p><h2 class=”body-h2″>What To Consider </h2><h3 class=”body-h3″>Encapsulation and compression</h3><p class=”body-text”>Our experts say styles with either (or both) encapsulation and compression are the best support features for intense workouts. If you’re moving in all directions, your boobs will be, too! Encapsulation means that bras have individual, contoured cups, while compression hugs everything in. Like our top pick from Under Armour—the Infinity 2.0 High Sports Bra—many of our experts’ favorite picks cradle and separate each breast. However, the amount of support needed will vary by your cup size.</p><h3 class=”body-h3″>Strap thickness</h3><p>Experts say a thicker width maintains shape better than thin straps over time, and adds much-needed support. Adjustable straps help you get the perfect fit, but be aware that they can loosen during activity. </p><h3 class=”body-h3″>Cup sizing</h3><p class=”body-text”>Bras labeled as small to extra large might not be as precise as those with cup sizes. Bras that specify both cup and band sizes offer a more tailored fit. </p><h3 class=”body-h3″>Materials</h3><p class=”body-text”>All our experts recommend high-impact sports bras made with quick-drying, sweat-wicking, or breathable materials, such as the below.</p><ul><li><strong>Elastane: </strong>This is a lightweight, stretchy fabric that will give your bra that snappy, elastic feel. This is the material to thank for a bra’s compression.</li><li><strong>Nylon: </strong>A soft, stretchy, and durable fabric that’s moisture-wicking—perfect for when you want to stay dry and keep sweat stains at bay during your workout.</li><li><strong>Polyester: </strong>A strong, water-resistant fabric that keeps you dry during exercise, but it’s not as breathable as elastane and nylon. It’s also very soft and smooth. </li></ul><h2 class=”body-h2″>How We Selected</h2><p>To curate our list, myself along with <a href=” Barnett, CPT,</a> an online fitness and wellness coach, and <a href=” Beebe</a>, a kettlebell coach and two-time USAPL (USA Powerlifting) National Qualifier, and fitness and commerce editor <a href=” Accardi</a> tested bras designed for intense workouts. Each style was rigorously tested for weeks through high-impact works like running, jumping rope, and quick, lateral movements to determine whether or not it was god-tier and worthy to be featured on our list. </p><p>We originally had three picks on this list when we first wrote this article, but we added seven more favorites to this list after months more testing. We found that the winners all provide high compression and support, wick away sweat, resist excess bounce, come in many different sizes, and have customizable features like zippers or hook-and-eye closure to get a snug fit. </p>” data-next-head/>
After testing dozens of high-impact sports bras for months, Barnett and Beebe concluded the Under Armour Infinity 2.0 High Sports Bra reigns supreme and offers the most support, even for larger chests. It checks off all the boxes that make a high-impact sports bra effective for intense physical activity whether you have a small or large chest.
Barnett and Beebe love that the encapsulated cups keep everything locked in without feeling suffocating. Barnett says the design delivers individualized support to each breast for a flattering, natural shape without pancaking the chest. They also both agree that the adjustable straps create a tailored, custom fit. Sizes range from XS to XL with each size offering A-C or D-DD cup size options. The U-shape at the front provides firm compression without digging into the armpits—a bonus if you struggle with chafing.
If you prefer a back and front clasp enclosure, this bra is the one for you. “The clasp in the back made it easy to take off after a sweaty workout—the adjustable and convertible straps clipping in the front also helped set this bra apart as most do so at the back,” says Beebe.
This bra was tested during every workout imaginable including strength training and cardio. Barnett and Beebe had the straps stay put and didn’t need to make any adjustments for the full duration of their workouts, even during explosive exercises such as burpees, high knees, and heavy lifts. “I took a cardio kickboxing class and felt very secure and supported the entire time—no adjustments needed for the full hour,” says Beebe.
The breathable fabric dries fast and doesn’t feel drenched when sweaty, making it okay to stay on post-workout. Plus, it has odor-control technology to keep stank away. (This is the only high-impact sports bra on this list with such a feature.) “I even stuck it in my gym bag after a workout and it didn’t smell when I took it out several hours later,” says Beebe. Despite going through multiple washes, the material still feels durable and hasn’t lost shape.

Running Girl High Impact Sports Bra
Now 21% Off
Pros
- Budget friendly
- Super breathable
- Is stylish and light rather than bulky and thick
Cons
- Seams can show through shirts
The most budget-friendly pick on this list, the Running Girl High-Impact Sports Bra is built for serious movement—think running, jumping, and all those sweaty, full-body workouts. It has molded cups that keep everything in place and adjustable, stretchy straps so you can dial in the perfect fit.
What stood out to me during testing was how breathable it felt, thanks to tiny perforations in the nylon-spandex fabric that let air flow through. Even though it holds you in with a secure, compressive feel, the material is soft and flexible like a second skin that moves with you, not against you.
I also love that it looks good. Unlike a lot of high-impact bras that lean bulky with thick straps and heavy padding, this one has a sleek, flattering design that doesn’t scream “gym.” The cutout in the back adds a stylish touch, so I have no problem wearing it solo with leggings on errands or a coffee run. Just note: the seams in the front can peek through lighter shirts, so that’s something to keep in mind.

Best Zip-Front
Shefit Ultimate Sports Bra
Pros
- Adjustable straps
- Removable Cups
- Front zipper and hook and eye closure
Cons
- A bit bulky with the zipper
Zip-front sports bras are a game-changer for bigger busts—no more awkward twisting into back closures. Instead, everything zips up snugly in front, locking you in right where it matters. While some styles can feel bulky, the Shefit Ultimate Sports Bra gets it right. It delivers serious support with a front zipper, adjustable shoulder straps, and a customizable ribcage band so you can fine-tune the fit. Bonus: hook-and-eye closures under the zip add an extra layer of hold, so there’s zero bounce, even during high-impact moves. This feature also helps eliminate chafing, which I appreciate.
I also love that the cups are smooth and flattering (not stiff or over-padded) and totally removable if you prefer a lighter feel. The fit is super inclusive, going all the way up to 6XL, which just reinforces how well it caters to larger chests. And thanks to the stretchy blend of nylon, elastane, and spandex, it hugs you in all the right places without feeling stiff or suffocating.

Best High-Impact Sports Bra For Smaller Chests
Brooks Crossback 2.0 Sports Bra
Barnett thinks the Brooks Crossback 2.0 Sports Bra is a solid choice for smaller chests (size C or below) because it doesn’t have as much stay-in-place power for those with larger breasts. Beebe thinks it fits women best with less muscle in the upper body and trap area because the straps can slide around those bigger muscles and don’t have as much grip. The straps aren’t adjustable, which is probably why this bra doesn’t accommodate larger chests and broad shoulders well. This bra uses band and cup sizing (30 A/B to 40 DD/E).
Beebe says while the bra was supportive, the straps didn’t stay in place, felt thin, and kept sliding during sprints, jumping, and kettlebell workouts despite being sweaty (which can cause the fabric to cling to the body). Barnett didn’t have that issue, so it all depends on your body type. It’s her go-to for runs, and she loves the snug fit and seamless design to help prevent chafing.
The breathable material dries fast after intense sweat sessions and the encapsulation cups feel durable. It feels super smooth against the skin, and the seamless fit means it’s perfect for layering—it won’t show any lines under your cute workout set!

Best High-Impact Sports Bra For Running
On Performance Flex Bra
Any runner with boobs knows that a sports bra with incredible support is a must. Whether you’re running fast or slow, the quick motion causes breast pain when nothing is holding them in place—especially for larger chests. So, a high-impact sports bra designed specifically for running deserves its own category.
As a fitness editor, seasoned runner, and On shoe stan, Nicolette Accardi had to test out the brand’s Performance Flex Bra. She doesn’t normally go for sports bras with encapsulation cups since she doesn’t need them (small boob probs), but she loves this style for long runs. The material feels so buttery smooth that it doesn’t chafe her armpit area, even after seven-mile runs. Plus, it offers full coverage to wear alone on the streets of New York City. Beebe agrees, although she says it was tighter under her armpit area and you may need to size up to find the right fit.
Our chests feel supported and secure whether we’re hitting slow or fast paces, and Beebe notes that this is also a great running and hiking bra for larger chests. Sizing ranges from XXS A/C to XL D/DD cups.
Each boob feels cradled and enclosed in the light padding for zero movement. The compression is tight but doesn’t make us feel constricted, which is impressive given the higher neckline and additional lower band. Accardi normally wouldn’t go for those features, but she was proved wrong. The cut-out back design is great for air circulation if you’re a heavy sweater as she is. The adjustable straps also didn’t budge, which Bebee struggled with when testing the Brooks Crossback 2.0 Sports Bra.
The sweat-wicking blend of recycled polyester and elastane fabric dried remarkably fast, although the band held onto sweat and stayed damp longer. Having a wet band clinging against Accardi’s back felt slightly uncomfortable, but it’s not a deal breaker. As for durability, this bra was able to withstand multiple washes and still looks new off the rack.

Best With Pockets
Bandit Running Scoop Neck Race Crop – Black
When I’m heading out for a run, I need a place to stash my apartment key, ideally without it jingling around in my pocket. That’s why I love this bra: it has three discreet pockets—two under the arms and one at the center-back—perfect for small essentials like my credit card and key. This is super useful when you’re doing a social workout, and you can grab a coffee afterwards without having to bring your wallet or bag. Bonus: the back pocket is roomy and sturdy enough to hold my phone, which is a rare and very welcome feature in a sports bra.
At first glance, it looks like a simple tank top, but hidden inside is a built-in shelf bra that actually does its job. I was surprised by how supportive it felt considering there’s zero bulky padding or thick straps. The magic is in the ultra-stretchy performance fabric, which offers light compression and supports your movements. I’ve taken it on several runs with no chafing (a miracle for me), and it offers just enough support for medium-impact workouts. It may not be as hardcore as some of the other bras on this list, but if you’re after something sleek, comfy, and functional without all the extras, this one’s a winner.

Most Customizable Support
Nike Women’s Indy High Support Padded Adjustable Sports Bra
Pros
- Comes in three support levels
- Wicks away moisture super quickly
- Not too tight around the band
Cons
- Padding is thick
This Nike sports bra really checks all the boxes—it’s adjustable, moisture-wicking, and padded, so you can go all out in high-intensity workouts without second-guessing your gear. One of my favorite features? It comes in three support levels (light, medium, and high), so you can choose what works best based on your chest size and workout style. Just a heads-up: the light support version has thinner straps. I went with the high support option, and it keeps everything locked in without feeling restrictive. The polyester-spandex fabric also wicks away sweat like a pro, keeping me dry from warm-up to cooldown.
Another win: the chest band lies flat without digging in or creating any awkward bulging. And if you like a snugger fit, the back hook-and-eye closure lets you tweak the tightness. The padding is on the thicker side with this version, so if you prefer a sleeker, more minimal feel, I’d recommend going for the medium support option instead. I wore this for a heavy lifting session last week— and although I got sweaty, the bra held up without feeling soggy or weighed down.

Best For High-Impact
Lululemon Go Further Bra With Support
Pros
- Doesn’t over accentuate the breasts
- Keeps me feeling locked in
- Breathable and light
Cons
- No adjustable straps
If you’ve ever found yourself mid-run wishing your sports bra had your back (and your front), meet the one that actually does: the Lululemon Go Further Bra. Engineered specifically for high-impact movement and long mileage, this bra delivers next-level support without sacrificing comfort or style.
What sets it apart? The encapsulated cups lift and separate without flattening, while padded adjustable straps and a customizable hook-and-eye closure let you dial in the perfect fit. It’s made with a supportive, sweat-wicking fabric blend of nylon and elastane, which stretches with you while keeping everything in place. And there’s also a mesh panel under the breasts that adds breathability exactly where you need it.
This is the bra I keep reaching for on long run days. It doesn’t shift, it doesn’t chafe, and it somehow makes me feel locked in and weightless at the same time. A rare combo. Whether you’re training for your next race or just out clocking miles, this bra goes the distance (literally!). One thing to keep in mind? It doesn’t have adjustable straps, so I’d recommend sizing down for a tighter fit. I do love that the straps are padded though, so they never chafe against the skin.

Most Versatile
Athleta Invincible Bra
Now 64% Off
Pros
- Smoothing and stretchy
- Great for all workouts
- Full coverage
Cons
- Not as moisture-wicking as others
The Athleta Invincible Sports Bra isn’t just built for high-impact workouts, it’s built for all exercises. Whether you’re sprinting through intervals, flowing through a power yoga class, or tackling back-to-back strength circuits, this bra shows up and holds strong. It delivers the kind of reliable, bounce-proof support that makes you forget you’re even wearing a bra (that’s saying something!).
What makes it so versatile? The wireless construction offers lift and support without any digging, while the high neckline and full-coverage design keep everything locked in, no matter the movement. Wide, stay-put straps and a breathable racerback let you move freely, and the adjustable back clasp means you can tighten things up or let them breathe, depending on the day.
Made from 100 percent nylon, it’s buttery soft but built for performance, so it’s stretchy and smoothing in all the right places. I’ve worn it for long runs, hot yoga, and even Pilates, and it never misses. Basically, if your workouts change daily, this bra’s the MVP that can keep up with all of them. One thing to note: I found that the fabric, while ultra-soft, can take a bit longer to dry post-workout, especially after those extra-sweaty sessions.

Most Comfortable
Spanx High Impact Sports Bra
Pros
- There’s no pinching or pulling
- No break-in period
- Super stretchy
Cons
- No pockets
The second I put on the Spanx FlexFeel Sports Bra, I was sold. No breaking-in period, no adjusting straps mid-workout, just cloud-like comfort paired with legit high-impact support. It’s one of those bras you almost forget you’re wearing (except you’re very aware of how good you feel in it).
Made with nylon and elastane, this bra is ultra-smooth, incredibly breathable, and has a stretchiness that moves with you, so there’s no pinching, pulling, or riding up. The bonded construction lies flat against your skin for a sleek, seamless fit, and the wide, adjustable straps give you that “just right” level of snug without digging in.
Even with all that softness, it’s made to handle high-impact days. Whether I’m logging miles, hitting a boxing class, or jumping into a HIIT session, it keeps everything supported and secure. And the scoop neck and smooth silhouette make it cute enough to wear solo with leggings.
One thing to note: While it nails comfort and support, it doesn’t have any pockets, so if you’re someone who likes to stash keys or gels mid-run, you’ll need to bring a belt or pair it with pocketed leggings.
