First Class Short Sleeve Tee (add.01)

This premium T-shirt is designed to deliver first-class relaxation, combining cutting-edge add.01 technology with an ultra-smooth and luxurious feel. A bold “Relax” print on the sleeve adds a stylish statement while the relaxed fit makes it ideal for unwinding at home.

Crafted using soft jersey fabric made from rare organic DCH cotton, a high-quality, extra-long staple cotton grown in limited quantities (only 0.025% of India’s annual cotton production). It is spun loosely for softness, gas-singed for smoothness, and bio-processed to reduce fuzz—resulting in a sleek, refined texture.
