Brand Story

“Born from a lost t-shirt. Natenshon spent a year and $40K in credit card debt trying to replicate the feel of a perfectly worn-in vintage tee. The result: absurdly soft fabrics with a genuine commitment to circular fashion.”

Notable Achievements
  • ◆Certified B-Corp with 81.8 impact score (top 0.5% of US apparel)
  • ◆Re-Spun program: 575,000+ tees diverted from landfills
  • ◆450,000-650,000 lbs of textiles upcycled
  • ◆Over 50 brick-and-mortar stores, plus two 1969 VW buses for pop-ups
  • ◆$215,000+ donated to environmental and social causes
Key Differentiator

Actually walking the sustainability talk. 39% sustainable fibers today, targeting 75% by 2030. Zero single-use plastics. The Re-Spun upcycling program is a real circular economy — not greenwashing.
