Description
A soft, garment-dyed tee that wears like a favorite from day one. The relaxed, heavyweight cotton holds its shape while the washed-in color and textured finish give the shirt lived-in character. Front art channels late-night, tech-wear vibes — a glitchy error-window and the tongue-in-cheek line “Error 404: Sleep Not Found” — so it reads like a quiet manifesto for night owls, coders, students pulling an all-nighter, and anyone who collects caffeine and late hours. Layer it under a flannel for studio sessions, wear it with worn denim for an all-day hackathon, or toss it on between naps and deadlines. The roomy fit, durable double-needle seams, and garment-dyed softness mean this will be the tee you reach for when comfort and mood matter more than matching the rest of your outfit.
