Proof of Concept Crewneck (S-3XL)
An idea, worn daily.
This crewneck is for people who build quietly. Who test, try, revise, and keep showing up.
PROOF OF CONCEPT isn’t a slogan here. It’s a reminder that ideas become real through consistency, care, and work.
Soft and midweight, this sweatshirt settles in like something you already trust. The minimalist front keeps the focus clear, while a small amber emblem on the back adds warmth and intention without distraction. It’s the kind of layer that fits into real life: early mornings, long projects, slow weekends, and everything in between.
Part of our February Black History Month curated collection, this piece reflects a belief in social, economic, and racial equity across genders. Not performative. Not loud. Just present. A quiet affirmation that everyone deserves space, resources, and recognition for their work.
Designed by a small business. Made to last. Priced with care so support stays mutual. This is about choosing thoughtfully, shopping small, and wearing something that aligns with how you move through the world.
Available in 8 considered colors.
