Women's Signature Classic & Basic Fit Long Sleeve T-Shirt

Available exclusively at the YJACK Seoul Now Pop-Up · September 22 – October 5, 2026 · 262 Mott Street, New York.

A women's long-sleeve crew neck T-shirt in a lightweight 155gsm EXFINA Cotton — the long-sleeve counterpart to YJACK's signature tee.

Made from 100% EXFINA Cotton — an extra-long staple cotton finished through YJACK's EUT process. The longer fibre leaves fewer exposed ends, so the surface holds up smoothly through washing and wear.

A quiet foundation piece for cooler months — layers under knits and blazers, or wears on its own with denim and a jacket.

EXFINA COTTON CARE
100% EXFINA Cotton is a premium long-staple fibre that requires gentle handling to preserve its hand feel and silhouette.

Washing
Hand wash or professional dry clean recommended.
By hand: use a neutral detergent in lukewarm water (up to 30°C / 86°F) and wash gently.
By machine: turn the garment inside out, place it in a mesh laundry bag, and wash alone using a neutral detergent on the wool or delicate cycle.
Do not use bleach or enzyme-based detergents, as they cause fibre damage.

Drying
Do not machine dry. Heat drying causes shrinkage and deformation.
Do not wring or twist. Press gently to release excess water, then wrap in a towel and press again.
Lay flat to dry in the shade, reshaping the garment to its original form.

Storing
Fold rather than hang to maintain shape.

Please Note
EXFINA Cotton is made from exceptionally long, fine fibres. Light pilling may occur from friction during wear — this is a natural characteristic of the material, not a defect.
Dark colours may transfer onto lighter garments through friction. Take care when pairing with light-coloured pieces.
