The Core Tees 3-Pack brings Katamu’s motto to life, with each pump cover representing a different stage of the process — Struggle through the hard days. Lift with purpose. Conquer what you came for.

Made from premium 100% cotton with an oversized gym fit, each pump cover delivers a heavyweight, comfortable feel built for training. Three shirts. Three words. One mindset.

Struggle. Lift. Conquer. Repeat.
