The Ultimate Heavyweight Pump-Cover. Step into the gym with the presence of an Upper Moon.

Featuring Douma on the back, this piece is designed for those who want their gym gear to tell a story while providing a massive, structured silhouette.

At a substantial 0.8KG, this isn't just a t-shirt—it’s armor.
