Women's racer back bras

Here, the Flex Racer Back Bralette is made with 91% organic cotton, and the Active Racer Back Bra has a shell made with 60% recycled nylon. Each is a racerback bra, with the straps drawn in towards the center of the back.

What is the difference between them?

The Flex Racer Back Bralette is the cotton one. Its body is made with 91% organic cotton, with elastane making up the rest, and its cup lining is a separate fabric: 90% polyamide with 10% elastane.

The Active Racer Back Bra is the stretch one. Its shell is made with 60% recycled nylon and 40% elastane, against 9% elastane in the Flex body. Its cup lining is made with 87% recycled polyester and 13% elastane. Each product page carries that style's own full composition and its care instructions.

Sizes and colors

Each style is sized XXS to XXXL, in letter sizes rather than band and cup, so the size guide on each product page is the one to read. Between them they come in Black, Cranberry, Night Sky, Pink, Soft Breeze, Summer Wine and Walnut. Black runs in each style. Cranberry and Soft Breeze are Flex colorways; Night Sky, Pink, Summer Wine and Walnut are Active ones.

Racerback bras at Organic Basics

A racerback bra is defined by its back, not by its support level, so the styles here are not substitutes for one another: the Flex Racer Back Bralette is a cotton bralette and the Active Racer Back Bra is a stretch bra. The product page for each sets out what it is made from and how to wash it.
