Composition

Body: 66% TENCEL™ lyocell / 32% organic cotton / 2% elastane.
Elastic: biodegradable rubber (30% natural kauchuk, 70% organic cotton).
Labels: 100% organic cotton.

Fabric

TENCEL™ lyocell is a cellulose fiber made from sustainably managed wood pulp using a closed-loop process recovering 99% of solvents. Blended with GOTS-grade organic cotton, it creates a silky, naturally antibacterial fabric that wicks moisture without chemical treatments. The 2% elastane provides shape recovery — the minimum needed for structure, nothing more.

Design Details

The zip longsleeve borrows its architecture from our bestselling merino version — high collar, front zip, fitted silhouette — and reimagines it in organic cotton + lyocell for warmer conditions and sensitive skin. The ruched detail sleeves add the signature texture that runs through every piece in this collection — from the strappy bra to the wide leg pants. Slim fit through the torso with enough ease for unrestricted movement. Layer it under the ballerina wrap or wear it standalone for studio sessions.

Care Instructions

Machine wash cold (30°C) on gentle cycle. Use mild or pH-neutral detergent. Lay flat to dry — never tumble dry. Do not bleach. Skip fabric softener — it coats fibers and reduces moisture-wicking performance. Store folded to prevent stretching.
