Sustainability

Tested, Tried & True: Independently lab-tested free from BPA and PFAS. Most brands won’t claim this — because they can’t.

Premium Performance Yarns: Our high-quality, fully traceable yarns are sourced through sustainable partners, including a family-owned mill in the U.S. These materials meet rigorous chemical safety standards and are independently verified for harmful substances through certifications such as STANDARD 100 and ECO PASSPORT by OEKO-TEX®.

Biodegradable Innovation: We use CiCLO®-enabled yarns—certified by ECO PASSPORT by OEKO-TEX®—that allow yarns like nylon and polyester to biodegrade in the environment more like natural fibers. Instead of persisting for centuries, these yarns break down in a matter of years when exposed to landfill or ocean conditions.

Recycled materials, minimal waste: Our commitment to protecting the planet starts with sustainable fibers and yarns. We use synthetic yarns made from recycled plastic bottles which helps remove ocean plastic and repurpose unused short fiber from the yarn spinning process. Our sports bras are designed to minimize waste and environmental impact—without compromising on performance or comfort.

Athletic, thin socks

"These socks fit well and feel nice for workouts. (They are thin, so they're not your ideal daily winter sock) Though I'd say I personally am looking for a little more cushion/ thickness in the socks I run in and workout in."
