Women's Sports Bras

Club Nala sports bras

Sports bras built ground-up for fuller boobs, not simply scaled up from a smaller cup. Wire-free and underwire high-impact options, available across C to J cups depending on the style and band size. 

How much support do you actually need

Match the bra to the workout and you stop the bounce, the shoulder ache and the post-run soreness. Get it wrong and you'll know about it by the second round of burpees.

Wire-free or underwire for high impact, the honest answer

Here's the thing most activewear brands won't tell you. A well-built wire-free sports bra can absolutely hold a fuller bust for medium impact, and plenty of high impact workouts too. Ours does. The band, the compression panels and the strap architecture do the job the wire would normally do.

But if you're a proper runner, sprinting or jumping at the top end of our cup range, an underwire will still give you a firmer anchor and less lateral movement. That's why we make both.

Why the trade-off? We’d rather give you the choice than pretend one option wins for every body. Love the freedom of no wire for the rest of your day? Browse our full range of wirefree bras. Prefer the hold of a wire all day? Our everyday underwire bras have you covered.

Getting the fit right for a bigger bust

The band does around 80% of the support work. If your band rides up your back, the cups are doing a job they were never built for, and the bounce follows.

Two quick checks. Slide two fingers under the band at the back. It should feel firm and level, not loose, not cutting in. Then do the jump test. Bounce on the spot for ten seconds. If your boobs move more than a small amount, the band is too loose or the cup is too small.

Bad fit shows up in obvious ways. Band riding up, boobs spilling out the top or sides, straps digging into your shoulders, wires poking your ribs. Our Fit whisperers deal with this every day, and the full Nala fit guide walks you through every check. Still not sure about your size? Use our Bra Size Calculator to find your perfect fit.

What MotionTech fabric actually does

MotionTech is 84% recycled nylon and 16% elastane. Not marketing speak, that's the actual composition.

The recycled nylon is a deliberate swap from virgin nylon. Same performance, better material choice, no sweeping green claims attached.

What that mix gives you: moisture wicking that pulls sweat off your skin so you're not squelching through the second half of a run, quick drying so it's ready for tomorrow, and stretch and recovery that holds its shape wash after wash rather than sagging out at the band.

The Club Nala range and who each bra suits

Three bras and one matching bottom, each built for a different type of mover. All of it developed and refined over 18 months on real bodies. 

Club Nala range compared

The High Impact Underwire is the heavy lifter. It has a moulding underwire, thick padded straps, full cup coverage and a J-hook if you want to wear it racerback. One 12H runner reviewer says she pushes it to its limits and it holds up well.

Prefer a set colour? Shop our black bras and blue bras. Club Nala comes in Licorice/Snow Cone and Space/OJ, plus brights like Dollhouse/Flame and Plum Juice/Apricot.

Sizing and where the range starts and stops

Club Nala sports bras are available across B to J cups, although the exact cup and band range varies between styles. The band range for sports bras is currently narrower than the main Nala range, at bands 8 to 22. If you sit at the fuller end of the band scale, check the Nala bra size guide before you land on a size.

If your exact size isn’t in a particular style, sister sizing usually gets you there. Drop a band and go up a cup, or the reverse, then run the movement test above.

Sports bra FAQs

What size sports bra do I need if I am a D cup or above?

Start with your regular Nala bra size and check it against the size chart for your chosen sports bra. If you're at the fuller end of the cup range, our bras for big boobs collection is worth a look for everyday wear too.

Can a wire-free sports bra really hold a big bust for running?

For most runs, yes, if the band fits properly and the cup size is right. For long distance running or sprinting at the top end of our cup range, an underwire will give you a firmer hold and less lateral movement. Both options exist for a reason.

What is the difference between low, medium and high impact?

Low impact is walking, yoga and pilates, minimal bounce. Medium impact is cycling, hiking and weights, some movement. High impact is running, HIIT, dance and anything with both feet off the ground. The higher the impact, the more support you need.

How should a high impact sports bra fit?

Firm but not painful. The band should sit level across your back and not ride up when you lift your arms. Cups should fully contain your boobs with no spillage or gaping. Do the jump test. If there's more than minor movement, size down in the band or up in the cup.

How do I wash my Club Nala sports bra?

Cold hand wash and line dry. Avoid the dryer, as heat can damage the fabric and shorten the life of your sports bra. 

How is MotionTech different from standard activewear fabric?

MotionTech is 84% recycled nylon and 16% elastane, blended specifically for boob support rather than general activewear. It wicks moisture, dries quickly and holds its shape wash after wash. The recycled nylon replaces virgin nylon in the mix.
