Shipping & Returns
Mummyduck Customs is designed in Helsinki, Finland. To keep delivery times short and shipping costs reasonable, our products are printed and fulfilled on demand by partner facilities in the USA, EU, and Japan, depending on the item and your delivery address. Orders to EU addresses are fulfilled from our EU facility where possible; some larger sizes are only printed in the USA, so those specific items may take a little longer to reach EU customers.
Processing and delivery times
Orders are typically printed and shipped within 2-6 business days. You will receive a shipping confirmation email with tracking information once your order leaves our facility. Actual transit time depends on your location and the carrier; please allow extra time for the postal service to scan and process tracking updates after pickup.
Shipping costs
Shipping costs are calculated and shown at checkout based on your delivery address, the items ordered, and the fulfillment location. US customers are charged standard US domestic shipping rates when their order ships from our US facility; EU customers are charged EU shipping rates when their order ships from our EU facility.
International orders and customs
We ship to most countries. Orders shipped internationally may be subject to import duties, taxes, or customs fees charged by your country upon arrival; these are the responsibility of the customer and are not included in our shipping charges or controlled by us. We are not responsible for delays caused by customs processing. If your country is not available at checkout, contact us at harri@mummyduck.com and we will do our best to add it.
Packaging
Apparel (t-shirts, sweatshirts, hoodies) ships in a protective plastic bag. Mugs and similar items ship in a cardboard box.
Lost, damaged, or delayed packages
If your package is lost, stolen, or arrives damaged, contact us at harri@mummyduck.com with your order number and we will arrange a replacement or resolve the issue.

Care Instructions
Care Instructions

Coffee starts the rider. Gasoline handles the motorcycle. Reversing the order is not recommended.
Caffeine & Gasoline is for mornings when breakfast can wait but the machine cannot. The garage is cold, the coffee is strong and something mechanical already wants attention.
This is the extra layer for cafe-racer people who regard a coffee stop as part of the maintenance schedule.
Why you'll wear it
- Gives cooler garage mornings another layer before the engine joins in
- Belongs beside the first coffee and the second attempt to start the bike
- Works at meets, workshop sessions and road-trip evenings
- Says what fuels the routine without dressing it up as philosophy
- Comfortable enough for the hours spent diagnosing a five-minute problem
The details
- Pre-shrunk cotton-polyester blend
- Classic fit

Sweatshirt
Built for the ride, not the showroom
Mummyduck doesn't make apparel for people trying to look fast standing still. This sweatshirt is for the actual ride — and everything before and after it. Coffee first. Then the road. The sweatshirt doesn't care which one fixed your morning.
What it's made of
Gildan 18000, 50% cotton / 50% polyester, 8.0 oz/yd² — heavy enough to mean something, soft enough you'll forget you're wearing it. Air-jet spun yarn for a clean feel against the skin, pre-shrunk so the fit doesn't lie to you later. Rib-knit collar with spandex, double-needle stitched at the collar, shoulders, armholes, cuffs, and hem — the places that actually wear out first. Quarter-turned construction, so no crease running down the middle like it's been folded in a drawer for a year. This is the one we'd actually wear, which is the only reason it's on the site.
Why the wait
Made on demand, no minimums. Yours gets built the moment you order it — that's why it takes a little longer, and why there's no stack of unsold hoodies sitting in a warehouse somewhere.
Where it's been
Knitted and dyed in Honduras and Bangladesh, put together in Nicaragua, Honduras, Bangladesh, or El Salvador. Zero recycled polyester, zero hazardous substances. One honest note: like most synthetic-blend fabric, this releases small plastic microfibers when washed — wash cold, wash less, it helps.
