I recently splurged $45 on an OSO shirt, and let me tell you, it has raised the 'bar' on workout attire – and I’m not just talking bench presses. The quality of this shirt is so amazing, I'm pretty sure it's woven from the whispers of ancient, muscular sheep. The fabric is so comfortable and durable, I suspect it could survive a tug-of-war between two bodybuilders arguing over the last scoop of protein powder. Wearing it, I feel like I could out-lift Atlas himself, and still look fresh enough for a post-gym selfie. If this shirt were a dumbbell, it'd be the one you'd curl with just to impress your crush. Five stars – would flex in again!
