Cirra High Impact Sports Bra - Unlined
Our sports bras are compression-oriented. We recommend that you order your typical size, plus one size up to try in your first order. We offer free shipping + free returns so you can order multiple and return what you don't want to help make sure you find the right size.
Most of our customers find our sports bras true to size, and the rest size up.
Size varies greatly based on measurements, breast tissue composition, intended activity, and personal preference. We have a size chart below for guidance...
To find your size, use a fabric measuring tape to measure the circumference around your rib cage right below your bust and around your bust at the widest point.
The chart below is for our standard sizes XS-XXL. If you find that you are at the upper or lower ends of the measurement range, you may want to consider our extended sizes which allow you to mix band and chest sizes. For more info on that, click here.

Customer Reviews
"No bounce, no chafe, no straps cutting into my shoulders and best of all it's actually breathable and dries quickly. Great design Lume Six!
Niki
"Fits like a dream. I put it on and forgot about it. It's that comfortable! I'm a runner, but was fully supported by this bra. Also, no pinching or cahfing. Thank you for solving my old sports bra problems!"

"I absolutely love this bra. I am a 34D and have struggled to find sports bras that fit both my rib cage and boobs well...it is the most comfortable, supportive sports bra I've worn."

Comfort-Focused Features
Alleviate Straps
Straps that lay flat with a bit of cushion to avoid creating a pressure point over the shoulder.
Halo Elastic Band
The foundation of support for any sports bra, our band stays connected with the rib cage without bunching up.
Streamline Seams
Say goodbye to chafing. Bonded seams are smooth against the skin to maximize comfort.
Mix & Match Sizing
Fine tune your fit with alternative chest and band sizing.
Our bodies are unique, and mix-and-match sizing allows you to find the perfect fit.
Unlined
The ultimate lightweight and fast-drying version of our sports bras. While our lightly lined versions have modest coverage, this style is minimal and provides maximum breathability.
