RUNNING GIRL’s most visible sports bra is the WX2667 High Impact Racerback. It tops the brand’s lineup in search results and in reviews alike.
We went through the listing details and plenty of buyer feedback to find out whether it is truly the best pick or simply the one Amazon puts in front of you first.

Fabric and Construction
The fabric is a moisture-wicking blend that the brand calls “naked feeling”. RUNNING GIRL uses the same second-skin material across most of its high-impact bras.
To limit chafing on longer runs, the panels are joined with flat lock seams.
Cut and Styling
This is a racerback with a longline cut. Wide, soft straps hold it up instead of skinny elastic.
The back features a cutout. Sewn-in padding in the cups adds shape without extra bulk.
What Buyers Report
The most common praise is support that does not feel like a compression vest.
Buyers say the wide straps do not dig into their shoulders during high-impact movement. They also like the soft inside lining, which does not scratch against the skin.
Value is the other repeated comment. Buyers feel they get plenty for their money, particularly when stacked against studio-brand bras that cost three or four times as much.
Getting the Size Right
Opinions on fit are divided. A number of buyers report that it fits true to size, but others find the same size runs small.
The split appears often enough to count as a real pattern and not a one-off complaint.
If you fall between two sizes, go up instead of down. That matters most for high-impact training, where a snug fit becomes uncomfortable quickly.
Versus Other RUNNING GIRL Styles and CRZ YOGA
Compared with the brand’s criss-cross styles, the racerback shape and longline cut cover more. That makes the WX2667 the go-to for higher-impact activity.
CRZ YOGA costs more and feels slightly softer, with a studio-leaning character. The WX2667 is cheaper and made with hard training in mind.
Is It Worth Trying?
Anyone who wants real high-impact support for running or HIIT, minus the studio-brand price tag, can treat the WX2667 as a sensible first purchase from RUNNING GIRL.
Size up if you land between sizes. Prices and ratings can shift over time, so confirm the exact figures on the current listing before ordering.
