Good
questions.

Three pieces: the No. 001 Origin and No. 002 Core hoodies, and the No. 003 Crew sweatshirt. Each one is made for exactly one person, once they claim it, and recorded under its own serial number. Think birth certificate, but for a hoodie.

Every piece gets its own serial number and owner record, issued once and never repeated. The design is shared; the piece is yours alone. Think of it like a fingerprint: plenty of hands, only one of yours.

It's a nicer word for ordering. Nothing sits in a warehouse waiting for you: your piece is finished once you claim it, embroidered and printed with its own QR code and serial number. Nobody else has worn it, tried it on or even stared at it.

Certified organic cotton and recycled polyester, mostly 80/20. Origin has a 100% organic cotton outside, and Crew is 100% organic cotton throughout. The fabrics carry GOTS, OCS, GRS, OEKO-TEX® Standard 100 and PETA-Approved Vegan certifications. That's a lot of letters, which is a good sign.

Full details on the Materials page.

Origin: regular fit with raglan sleeves, true to size. Core: structured regular fit, true to size. Crew: regular fit, but it runs small, so order one size up from your usual US size.

Every product page has a size chart in inches under "Size & fit". Tip: lay a hoodie you already love flat and compare. It never lies.

Wash cold and inside out, and skip the bleach and the dry cleaner. Tumble dry low for the hoodies; let Crew air dry. Treat it like it's one of one. It is.

It's your piece's link to its record. Point any phone camera at it and it opens the Verify page with your serial filled in. No app, no account, no dance.

In your shipping confirmation email. Or scan the QR code on the back. Or type it into the Verify page. We made it very hard to lose.

After a serial checks out, enter the zip code the piece was shipped to. It unlocks your personal ID: the piece number, your first name and the year you claimed it, followed by a code no other piece has. Consider it the secret handshake.

No. A scan only confirms the piece is real, which one it is and when it was issued. Your name stays out of it unless the matching zip code is entered. Admirers can admire from a distance.

It still verifies as authentic for whoever owns it next. The personal record stays with its first owner. You'll always be the original.

Your piece is made in 2–5 business days, and most orders arrive within 7–9 business days in total. You'll get an email with tracking and your serial when it ships. Good things, waiting, etc.

Free, on every order. We checked. Twice.

Email support@wearsingle.com as soon as you can. Once your piece goes into production it's already becoming yours, so it can't be changed or cancelled.

Email support@wearsingle.com within 30 days with your order number (and a photo, if it's damaged). We'll make you a brand-new one and cover all the shipping. You don't send anything back. Carriers have bad days. You shouldn't have to.

Yes, within 14 days of delivery, two ways:

Donate it. Give it to a charity you like, email us a photo of the donation receipt and your order number, and we'll refund you in full. Nothing to pack, and someone gets a great piece.

Send it back. Email us first for instructions. It needs to be unworn and unwashed, you cover the return shipping, and we refund your order once it arrives.

Full details in our returns policy.

Same options as any return: donate it and send us the receipt for a full refund, or send it back at your cost. Then claim the right size. Your old piece keeps its serial, so somebody out there gets a very well-documented hoodie.
