HercLeon launches HercShirt V5.0, a 30‑day odor‑free t‑shirt

American startup HercLeon has introduced the HercShirt V5.0, a t‑shirt that the company claims can remain clean and free of unpleasant odors for up to 30 days without being washed. The fabric is woven with seven active elements – copper, silver, zinc, gold, volcanic ash, and two undisclosed components – that provide antimicrobial and odor‑absorbing properties.

The product is offered in three protection levels: a budget version lasting three days, a standard version for two weeks, and a Max version that maintains freshness for a month, priced at $39, $79 and a higher tier respectively. The shirt is initially available in black, with additional colors planned, and shipments are expected to begin in early November. HercLeon notes that the shirt does not replace personal hygiene; stains and heavy dirt will still require washing, and no independent scientific studies have verified the 30‑day claim.
