Size Guide & FAQs

Size Guide

Our patent-pending sports bras are unlike anything you’ve worn before. When selecting your size, keep in mind that the HI-band is positioned above the bust and fully rotates to the back clasps (see below illustrations). If you are in between sizes, we recommend that you size up. Email support through the Contact Us page, and we'll happily assist you in your size selection.

*Your band width will be the most accurate bra fit (e.g. 32 will likely be size small regardless of cup size).


If you're between sizes, consider that all of our sports bras are constructed with the HI-band, which is positioned above the bust, and wraps around to the back clasps (see image above). Most of our customers size up when between sizes, and are able to adjust the back clasp hooks for a custom waistband fit. We use premium performance fabrics with superior compression and shape retention - so there is no need to size down to make the garment hold tighter. Based on customer reviews, our sports bras tend to run small.
