What is Spandex (8%)?

Spandex is a synthetic fiber known for its exceptional elasticity. It is made from a block copolymer that includes polyurethane, developed through a complex chemical process. This fiber is commonly used in the textile industry.

Common in activewear, Spandex is used primarily for its stretchability and comfort. It provides a snug fit and flexibility in clothing such as workout apparel, sports bras, and other performance garments. While it is favored for these properties, Spandex does not have a significant impact on health as it is not consumed or absorbed through the skin.

When you see Spandex listed on a label, it usually indicates a stretchy and form-fitting fabric. It is widely used in combination with other fibers to enhance the texture and flexibility of the material.

Commonly found in: Workout Shorts, Sports Bras, Workout Tanks, Bras

Benefits

Provides elasticity and comfort in fabric, particularly for activewear.

FDA

Research

Scientific studies focus on the mechanical properties of Spandex rather than its health effects since it is not absorbed or ingested.

Vegan

Spandex is a synthetic fiber and is suitable for vegans as it does not involve any animal-derived components.

Scout's take

The 8% spandex provides the stretch and recovery the bra needs to hold support. In a lab-verified PFAS-free fabric that is 92% GOTS organic cotton, this share is a functional necessity rather than a source of exposure.

MATE holds the Organic Stretch platform to 8% spandex — the minimum that keeps the legging moving and holding shape. At this share, in a fabric free of BPA, PFAS, and formaldehyde, it is a functional necessity rather than a source of exposure.

The 8% spandex is what gives the bra its stretch and the recovery it needs to keep its shape and support through a workout. In a GOTS-certified fabric with no polyester or nylon anywhere in it, this share is a functional necessity rather than a source of exposure.

Held to 8% — the minimum a biker short needs to retain its shape and stay opaque through movement. At this share, alongside a 92% organic cotton base, it is a functional necessity rather than a source of exposure.
