It’s Always Layer 1 T-Shirt
For anyone who works in networking, this joke needs almost no explanation.
Featuring the seven-layer OSI model with Layer 1 — Physical highlighted alongside a disconnected Ethernet cable, the design captures one of IT’s oldest troubleshooting truths: before blaming software, protocols, routing or anything complicated… check the cable.
Simple, technical and painfully relatable, it’s made for network engineers, sysadmins, helpdesk teams and anyone who has spent far too long diagnosing a problem that turned out to be something embarrassingly physical.
Seven layers of troubleshooting. One loose cable.
