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.
