Wear it for them.
When a wildfire, flood, or hurricane hits a community, we put up a shirt for it. You buy one, it ships in days, and $15 goes to a relief fund working there. Then we publish the receipt.
On sale now
1. Buy the shirt
One shirt, one price, one named fund. Never "a portion of proceeds."
2. Wear it in days
Ships in 3–5 business days. No pre-order window, no month-long wait.
3. See where the money went
$15 from every shirt goes to the fund. When the campaign closes we publish how many sold, how much was sent, and when.
