Z24 Athletic Baggy Shorts, Black — 530GSM Organic Fleece-Back Jersey

Most athletic shorts are designed to feel light.

The Z24 is designed to feel intentional.

Constructed from a dense 530GSM 100% organic fleece-back jersey, these shorts bring atelier-level textile engineering into athletic wear. The face of the fabric carries a refined cotton luster — a natural, elevated shine that reflects light without looking synthetic. In hand, it feels substantial. Controlled. Luxurious.

Turn it inside and the fleece-back construction delivers soft thermal comfort while maintaining airflow and breathability.

The baggy athletic silhouette creates room for movement and circulation. The weight anchors the drape. The structure prevents collapse. This is cotton performing at a level most brands reserve for outerwear — not gym shorts.

No petroleum blends.
No plastic gloss.
No flimsy mesh interiors.

Just engineered organic cotton built to move.

At 7thearthstudios, fabric character comes before convenience.

All of our fabrics are fully finished, refined, and production-ready. Shrinkage is minimized through controlled compaction and dyeing processes carried out at certified mills. However, unless a garment is explicitly specified as fully pre-shrunk (such as our G32 Heavyweight Shirts), we intentionally avoid aggressive garment washing.

While garment washing can further reduce shrinkage, it often compromises the fabric’s natural structure, loop definition, and surface character. Preserving these qualities — the weight, texture, and integrity of the cloth — is central to how our garments are designed to wear and age.

A 3–5% shrinkage on the first wash is natural and expected for most of our garments. When washed and cared for correctly, the fabric maintains its form, finish, and hand-feel over time, remaining consistent and refined through repeated wear.

Anyone can claim to sell “organic.” Most don’t have proof.
