HIGH FREQUENCY
Turn up your vibe.
The HIGH FREQUENCY tee is built for those tuned into the moment — elevated minds, deep sound, and raw energy. Featuring a bold, distressed olive green design with clouded speaker smoke printed on the front, this shirt brings together streetwear edge and 4/20 energy.
A small, stacked “IT’S A PROBLEM!⚠️ SINCE 2010” mark is printed on the upper back — a subtle nod to legacy, identity, and the ones who move different.
