Why You’ll Love It
210gsm SeaCell™ jersey — technical-weight, breathable, soft against skin
68% TENCEL™ Lyocell — wood-pulp cellulose, smooth as silk, breathable as cotton

Elevated high-set collar — modern, sculpted neckline that lifts the silhouette
Boxy-but-fitted cut — tailored through the chest and shoulders, relaxed at the waist
Soft as silk, breathable as linen — a fabric that does both at once
Naturally moisture-wicking — pulls sweat off skin as vapor before it becomes wet
Naturally resists bacterial growth and odor — seaweed minerals stay active wash after wash
Chlorine-free finish — plastic-free, machine-wash-friendly 100% cotton stitching — biodegradable and skin-safe
OEKO-TEX® STANDARD 100 certified — tested against 1,000+ harmful substances
Radically reduced microplastic shedding — 97% cellulose-based fiber vs. 100% plastic in polyester activewear
Composition
Fabric: 68% TENCEL™ Lyocell / 29% SeaCell™ / 3% Elastane (210gsm) Thread: 100% cotton Color: Anthracite
Fit
True to size. The cut is structured through the chest and shoulders with a clean drop straight through the body — boxy but not loose. The elevated collar sits high on the neck for a more architectural finish than a standard crew. Designed for training, daily wear, and the moments in between. If you are between sizes, stay true for a fitted athletic cut or size up for a relaxed silhouette.
The ZUBEK Difference
SeaCell™ is what happens when seaweed meets cellulose science. The fiber is spun from wood pulp and infused with Icelandic 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 menswear 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), inside out, on gentle cycle. Lay flat to dry — never tumble dry. Do not bleach. Skip fabric softener — it coats fibers and reduces breathability. Iron on low only if needed. Store folded, away from direct sunlight. SeaCell™ is naturally odor-resistant — wash less, wear more.
