18G Sports Bras

Our 18G Sports Bras Don’t Break A Sweat

If you’ve ever tried to exercise in a sports bra that wasn’t built for a true 18G size, you know the pain. Bounce, spillage, chafing, and a whole lot of regret. Rose & Thorne 18G sports bras are different. They’re designed to give you full support when you’re at your most active, whether that’s a high-intensity class, a power walk, or just chasing your kids around the park. No compression-only styles. No generalised “XL” sizing. Just genuine support that lets you perform at your best.

What Goes Into Our 18G Size Sports Bras 

Our 18G plus size sports bras feature full-coverage cups that encapsulate rather than flatten, wide straps that stay put, and a secure underband that won’t budge mid-workout. Our Premium Support features are built into all 18G size sports bras, helping to bring breast tissue forward and reduce sideways movement - so you’re supported from all angles, not just squashed in place. You can also choose between underwired (Active Bra) and wirefree (Sports Bra) styles, depending on your personal preference. And best of all, with our Forgiving Fit technology, you won’t have to buy a new bra if your shape fluctuates slightly over time. 

What To Look For In An 18G Sports Bra

The right 18G sports bra should hold, not compress, and feel firm without being claustrophobic. Prioritise breathable materials, adjustable straps, and sizes that are specific to your band and your cup size. Whether you’re stretching or sprinting, Rose & Thorne 18G sports bras make sure you move with confidence.
