COTTON

Cotton readily absorbs and retains moisture, making fabric heavier and slower to dry. Conventional cotton cultivation can also require substantial water and pesticide inputs.

POLYESTER / NYLON

Polyester is the same polymer used in many beverage bottles. Nylon is a polyamide. Both can shed persistent plastic microfibres, while some performance finishes contain PFAS.

SAFE TO TOUCH + SAFE TO DEGRADE

EU label

Our degradable SMART stretch isn't simply elastane.

The stretch fibre in Drop 01 appears on the EU label as 'Elastane.' Here's why, and what that means.

EU regulations require our stretch fibre to be labelled as 'Elastane' because it is the official fibre category. But not all elastane is the same.

Our Smart Stretch is OEKO-TEX® STANDARD 100 Class I certified for stringent next-to-skin safety, engineered to break down under specific end-of-life conditions without releasing harmful substances, awarded Cradle to Cradle Material Health Gold, and Hohenstein environmentally tested.

'Elastane' is the regulatory name for our choice of responsible technology.
