Built for pressure.

The Progress(ive) Performance Tee is part of the collaboration between Dark Yarn and Robert L. Arnold (@defiance13) — a collection created at the intersection of activism, accountability, and everyday visibility. Designed for people who refuse to disengage, this piece represents movement in every sense of the word: physical, cultural, and political.

Constructed from premium moisture-wicking performance fabric, this tee is engineered to keep up with intensity. Lightweight, breathable, and built with odor resistance, stain release, and UV protection, it’s designed for workouts, long days, difficult conversations, and showing up when it matters most.

Because resistance isn’t passive.
Neither is this shirt.

Every Progress(ive) purchase directly supports democracy defense and equality initiatives helping fund independent media, civic engagement, and real-world action through collective economic pressure.

No billionaires. No corporate puppeteers. No performative activism.
Just people moving resources toward something bigger than themselves.
