Essential Cooling Performance T-Shirt “Core Protocol” Built for heat, coded for movement.

The Core Protocol Tee is engineered for heat, hustle, and high output. Built from lightweight cooling performance fabric, it keeps airflow moving while you stay locked in. The bold BLOCKWEAR chest hit and distressed Bitcoin emblem bring that raw, urban‑tech attitude — a signal that you operate on your own chain. Soft, breathable, and cut for everyday motion, this tee is made for grinders who stay active, stay sharp, and stay in protocol.
