Shipping & Returns

Order changes

Every tee is printed to order, so production starts shortly after checkout. You have a 12-hour window to change size, color or address. After that the order is already moving and we cannot alter it.

Check the measurement notes before ordering - the Gildan 64000 is a slim, side-seamless fit. If you are between sizes, size up.

Shipping

Printed and shipped from the United States. Production takes 1-2 business days, then 2-5 business days in transit - about 3-7 business days in total. Free U.S. shipping on orders of 2 or more tees.

Returns

If your tee arrives wrong, damaged or defective it is eligible for a full refund or replacement - just tell us within 30 days. Because each shirt is made to order we cannot take returns on a change of mind, but if something is not right, email hello@moshtee.com and we will sort it.

Care

Treat it like a jacket you actually care about:

- Wash inside out, cold.
- Gentle detergent. No bleach, no fabric softener on the print.
- Do not tumble dry hot. Air dry if you can.
- Iron inside out, low heat. Never iron directly on the print.

Do that and the print outlives the band.

Pavel and Gabriele at the System of a Down show in Warsaw, July 2026, crowd of tens of thousands behind them

System Of A Down, Warsaw, 19 July 2026.

This July we drove to Warsaw for System Of A Down. Tens of thousands of people, all of them moshing, and nearly every one of them in a black shirt with a band on the front. Everyone in that stadium already owns the band shirt. Nobody is selling them the rest of it — the Monday morning, the office, the back that no longer forgives the pit. We do not make band merch. We bring metal into daily life.

Every design concept is mine, and every one of them is original. Gabrielė is the one who tells me when a joke does not land. We are in Lithuania; a print partner in the United States prints and ships, so your shirt is printed in the US and posted in the US. And hello@moshtee.com comes to me — I am the one who answers it.
