Listings show several modal blends: simple modal with spandex; a common women’s blend of 93% modal/7% spandex; and other options such as 75% modal/17% nylon/8% spandex.
Many modal bras use seamless or knit construction with wireless cup designs. Support and coverage range from medium to full, and some styles include removable padding for adjustable shaping.
Modal bras are offered as pullover styles and as garments with back closures (back-hook or hook-and-loop). Common back styles include U-back, crisscross, and scoop designs.
Strap designs commonly include adjustable straps and convertible styles. Some bras offer front-adjust options or convertible tank-to-X/back and crisscross configurations for versatile wear.
Many modal bras feature breathable, moisture-wicking fabrics and 4-way stretch for a flexible, comfortable fit.
Sizes range from girls’ sizing through women’s sizes. Some listings use XS–XXL for general sizing (including options for fuller busts), while others provide band and cup ranges such as 32A through 44I.
Some hands-free pumping designs were tested to hold more than 16 ounces while double pumping. Certain models also mention optional sling support for heavier pumping.
Some listings note OEKO-TEX STANDARD 100 certification for the primary body fabrics and include certificate numbers.
