Alta Medium 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
"I took the Alta on my backpacking trip and I really liked the bra. I packed two bras. I wore the non-Alta on the first day, then switched to the Alta for the rest of the trip. I really noticed a difference in how it wore (felt like nothing on)..."
Jean
"This sports bra is so comfortable and supportive. Easy to take off after a sweaty work out without any hassle. I love when I'm wearing it, I literally do not feel like I'm wearing anything - but yet totally supportive."
Brenna
"I love this sports bra. It is light and breathable while still being supportive. It wicks away moisture and dries very quickly. Yes, it is more expensive, but will last and works much better than cheaper sports bras...well worth the money."
Greta
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.
