You know that moment mid-workout when you’re dripping in sweat, and your sports bra feels like a wet towel stuck to your skin?
Yeah… that’s not fun.
The truth is that the fabric of your bra can make or break your comfort. The right sports bra material can keep you cool, supported, and confident — no matter how hard you move. The wrong one? It can leave you hot, sticky, and counting down the minutes until freedom.
So, let’s break down what makes the best material for sports bra comfort, support, and breathability — and how to find your perfect fabric match.

Not all sports bra fabrics are created equal. Some work as hard as you do, while others… well, give up halfway through your run.
Here’s the lowdown on the materials that keep you moving and comfortable:
Polyester and Nylon — The Power Duo
These two are the MVPs of the sports bra world. They’re lightweight, breathable, and (thankfully) fast-drying. They pull sweat away from your skin, so you stay cool and dry during your workout.
Most high-impact favourites, like the Panache Sport Endurance or Shock Absorber D+ Classic, use polyester blends because they’re durable and ready to take on the sweatiest sessions.
Elastane (aka Spandex or Lycra)
This little miracle worker is what gives your bra its stretch. It moves with you and snaps back into shape every time. Without it, your sports bra would feel stiff and unforgiving — no thanks!
Cotton — Soft but Sweat-Loving
Cotton feels amazing against the skin and is great for low-impact workouts like yoga, walking, or lounging. But here’s the catch: it soaks up sweat and doesn’t dry quickly. So, if you’re heading for a HIIT session, cotton might not be your best friend.
Mesh — The Breathable Bonus
Mesh panels are like open windows for your skin. They add airflow and reduce overheating — especially under the bust and across the back.
Moral of the story? The best sports bras use a mix of these materials to balance stretch, support, and breathability.
How Does the Material Affect Performance and Comfort?
Ever wondered why some bras feel buttery soft while others feel like armour? It’s all in the fabric.
Here’s how material impacts how you feel and perform:
Sweat Happens — Wicking vs Absorbing
Moisture-wicking materials (like polyester) draw sweat away from your skin and help it evaporate quickly. That means no damp, sticky feeling.
Cotton, on the other hand, absorbs sweat — great for comfort, not so great for marathons.
Keep Your Cool
Workout intensity up? You’ll want fabrics that breathe. Mesh panels and synthetic blends allow air to circulate and stop you from overheating.
Smooth and Soft
No one likes chafing. The best material for sports bra comfort should feel smooth against your skin. Look for soft inner linings or brushed fabrics that feel gentle, even during long sessions.
Stretch that Moves With You
Elastane is your best friend here. It lets your bra move naturally with your body — no pinching, pulling, or awkward shifting mid-workout.

Quick tip:
How the Material Affects Support and Fit
Here’s something most people don’t realise: your sports bra’s support doesn’t just come from the design — it comes from the material.
Firm Fabrics Mean Strong Support
The tighter the weave, the stronger the support. That’s why high-impact bras for larger busts often use thicker, structured fabrics. They hold everything in place without feeling restrictive.
Stretch Fabrics Mean Better Fit
Elastane adds that comfy “second skin” feel. It helps your bra contour to your shape and stay supportive, even as you move.
Double Layers for Extra Comfort
Some of the best sports bras feature double-layered fabrics — a sturdy outer layer for support and a soft inner one for comfort. It’s like having armour on the outside and clouds on the inside.
Durability and Care Matter
Even the best material won’t last forever. Avoid fabric softeners (they weaken the elastic fibres) and always air-dry your bras. It keeps them stretchy and supportive for longer.
One customer laughed and said, “My Panache Sport has outlasted three pairs of running shoes — and still feels amazing!” That’s the power of good material.
If you’re unsure whether your bra is still giving enough support, check your fit using our Determine Your Size guide. It only takes a few minutes and can save your shoulders from a world of pain.
When it comes to the best material for sports bra comfort and support, it’s all about balance.
Love intense workouts? Go for polyester-elastane blends with mesh for breathability.
Prefer gentle, low-impact movement? Cotton-rich styles feel soft and relaxed.
The perfect sports bra material should keep you cool, dry, and supported — from warm-ups to cooldowns (and even coffee runs!).
