Why This One

A Firm Legging With A Paper Trail

Most leggings ask you to trust adjectives. This one lists its numbers: the bottle count, the fabric split, the certification, the size run.

01

Compressive and squat-proof

A firm, ultra-high rise knit with 4-way stretch that moves with you, never against you. Squat-proof is the product page's own word.

02

Soft where it counts

Double-sided mossing makes it plush inside and out. Sweat-wicking, with a sleek matte finish instead of shine. It even resists pet hair and lint.

03

Recycled, and certified

79% recycled water bottles (RPET) and 21% spandex, in OEKO-TEX Standard 100 certified recycled fabric. Safe for you, sustainable for the planet.

The Mechanism

How 25 Bottles Become One Legging

Recycled polyester is a real supply chain, not a vibe. The short version takes four steps.

Collect

Used PET bottles are gathered, sorted, and stripped of caps and labels.

Chip

The plastic is washed and shredded into flakes, then clean pellets.

Spin

Pellets are melted and drawn into a fine polyester yarn.

Knit

The yarn becomes a compressive knit, cut and sewn into the legging.

Built To Stay In The Rotation

A legging that starts as recycled bottles should not end as fast fashion. The care routine is simple and keeps the fabric firm.

  • Wash cold and dry flat
  • Always wash with like colors
  • A microfiber filter or filtering wash bag is recommended

Quality, straight from the page
