This long sleeve makes a perfect gift for dads who know that bedtime is the real finish line. Ideal for Father’s Day, birthdays, holidays, or everyday wear, the Days of Slumber long sleeve is built for dads running on low sleep and high responsibility — the ones racing through each day just to make it to lights out.

Designed in-house and released exclusively by Dad To The Bone USA, the Days of Slumber long sleeve is a bold nod to exhausted fatherhood and the grind that comes with it. Created by dttbUSA, this piece captures the dad to the bone mentality — pushing through fatigue, showing up anyway, and laughing at the chaos along the way.

The Days of Slumber design blends retro racing energy with modern dad humor, turning sleepless nights into a badge of honor. It’s for dads who live in a constant race against bedtime and wear their exhaustion like a trophy.

As part of the official Dad To The Bone USA collection, this long sleeve features brand-forward artwork created entirely in-house by dttbUSA. It’s intentional, expressive, and built to stand apart from trend-driven designs.

Constructed on our premium long sleeve tee platform, the Days of Slumber long sleeve delivers all-day comfort, dependable durability, and an easy fit designed for real life. Perfect for layering, cooler weather, or long days that start early and end late.
