Out of RUNNING GIRL’s whole sports bra lineup, the WX2667 High Impact Racerback is the one that keeps coming up first in search and in reviews. I went through the listing details and a stack of buyer feedback to see whether it’s actually the pick, or just the one Amazon shows you first.
What it’s made of
The WX2667 uses RUNNING GIRL’s “naked feeling” moisture-wicking fabric, the same second-skin blend used across most of the brand’s high-impact bras. Flat lock seams run along the panels specifically to cut down on chafing during longer runs.
It’s built as a racerback with a longline cut and wide, soft straps rather than thin elastic. The back has a cutout detail, and the cups use sewn-in padding for shape without added bulk.
What buyers are actually saying
The recurring praise across reviews is support without feeling like a compression vest. Buyers specifically mention the wide straps not digging into shoulders during high-impact movement, and the inside lining feeling soft rather than scratchy against skin.
The other repeated comment is value. People call it good money for what you get, especially compared to studio-brand bras three or four times the price.
Sizing notes
Sizing feedback splits two ways. Some buyers say the WX2667 runs true to size, others say the same size runs smaller than expected. That split shows up often enough that it’s worth treating as a real pattern, not just a one-off complaint.
If you’re between two sizes, size up rather than down, especially if you plan to wear it for high-impact training where a snug fit gets uncomfortable fast.
How it compares
Inside RUNNING GIRL’s own catalog, the WX2667 is the go-to pick specifically for higher-impact activity, where the racerback and longline cut give more coverage than the brand’s criss-cross styles. Against a pricier alternative like CRZ YOGA, you’re trading a slightly softer, studio-leaning feel for a lower price and a bra built more for hard training. I broke that comparison down fully in RUNNING GIRL vs CRZ YOGA.
Should you buy it
If you want real high-impact support for running or HIIT without paying studio-brand prices, the WX2667 is a reasonable first bra to try from this brand. Size up if you’re in between, and check the current listing for the exact price and rating before you order, since both can shift over time.
