Step into effortless style and comfort with this unisex premium T-shirt—crafted from 100% combed cotton, the fabric delivers a soft, breathable feel with a smooth finish. The regular fit and classic crew neck create a timeless silhouette, while the pre-shrunk construction helps maintain its shape and size wash after wash.

Inspired by JavaScript’s native Number.isInteger(400), this design reinterprets the syntax as Tee.isInteger(400)—a conceptual twist that turns code into identity. By replacing the built-in object with Tee, the statement reads like a custom class where the garment itself becomes the subject—as if it’s being validated as an integer 400.

Available in two refined dark tones: Navy (images 1–4) and Petrol Blue (images 5–8). Choose Navy if you prefer a deep black-blue that feels clean, simple, and easy to pair with anything. Choose Petrol Blue if you want a softer blue-green that feels more distinctive while still staying calm and minimal.

Whether styled casually or elevated for a cleaner look, this T-shirt is designed for everyday versatility.

Care Instructions: To maintain the quality, fit, and finish of this T-shirt, machine wash cold with similar colors. Turn inside out before washing and use a gentle cycle with mild detergent. Do not bleach or use fabric softeners. Do not tumble dry—air dry in shade to preserve shape and fabric integrity. If needed, use a cool iron inside out and avoid direct contact with prints.

Size Guide

Width in the table above refers to the Garment Width (measured flat, pit-to-pit).

For a more accurate fit, use Body Chest Fit as your primary reference when selecting your size. The formula is (Garment Width × 2) − Ease, with an 8 cm ease applied.

S: 86–94 cm
M: 96–104 cm
L: 105–113 cm
XL: 114–122 cm
2XL: 120–128 cm
3XL: 128–136 cm

Fit note: Designed for a standard fit that sits close to the body.

If you’re between sizes, choose based on your preferred fit. For example, a 104 cm chest sits at the upper end of M (96–104 cm) and just below L (105–113 cm)—choose M for a regular fit, or size up to L for a more relaxed, looser fit.

In the product images, the male model is wearing size M and the female model is wearing size S.
