Fit

True to size. The 210gsm jersey moves with the body — flexible across the hips, structured through the waistband, comfortable on the thigh. Designed for low- to high-impact movement (running, training, hot yoga, daily wear). Built to handle real sweat without holding it against skin. If you are between sizes, size down for a snugger athletic fit or stay true for a relaxed cut.

The ZUBEK Difference

SeaCell™ is what happens when seaweed meets cellulose science. The fiber is spun from wood pulp (TENCEL™) and infused with seaweed extract during production — locking minerals, antioxidants, and trace elements directly into the fiber structure. Those compounds remain in contact with your skin every time you wear the fabric, every time you sweat into it, every wash cycle.

Polyester does the opposite. It traps heat against your body, holds moisture, breeds bacteria, and sheds microplastics into your skin every time you move. Performance polyester is finished with PFAS-based water repellents that absorb through warm, open pores. SeaCell™ is what activewear should have been the whole time — a fabric that performs because of what it is, not because of what's been added to it.

Care

Machine wash cold (30°C) on gentle cycle. Lay flat to dry — never tumble dry. Do not bleach. Skip fabric softener — it coats fibers and reduces breathability. Store folded, away from direct sunlight. SeaCell™ is naturally odor-resistant — wash less, wear more. See full care guide.

OEKO-TEX® STANDARD 100 certified — every component independently tested against 1,000+ harmful substances and verified below scientifically established thresholds. No PFAS, no PFC, no quick-dry chemistry, no stain repellents.
