Signature Collection Long Sleeve Tee - Black

Elevate your everyday rotation with our Signature Collection Long Sleeve Tee, the next evolution of our core essential. Designed for extended wear and cooler days, this piece carries the same luxury streetwear foundation as our short sleeve—refined for the season ahead.

Crafted from 100% organic cotton sourced from Portugal, this long sleeve features a 240 GSM heavyweight construction, delivering a premium hand feel with structure that holds its shape over time. The boxy, oversized silhouette and dropped shoulders maintain a relaxed, confident fit built for layering or standing alone.

The shirt is finished with our signature flocked logo on the chest—a subtle, textured detail that adds depth without overpowering the design. Clean, intentional, and unmistakably ILL.

Designed with 1x1 ribbing with 5% Lycra at the collar and cuffs, and pre-shrunk to minimize shrinkage (0–3%), this piece is made to wear well now—and years from now.

This isn’t just a long sleeve—it’s a seasonal staple. The Signature Collection Long Sleeve Tee bridges form and function, offering elevated comfort, durability, and understated style for those who value quality over excess.

Same fabric. Same standard. Extended season.
