Offcut makes baseball caps out of offcuts: surplus or unneeded fabric that clothing manufacturers would otherwise throw away. Very occasionally, they may release something that's not a hat; one example is a leather luggage tag they made available to Kickstarter backers a while ago.

All their designs are very limited edition. Sometimes they only have a single blanket's worth of material to work with, so they may make only fifty, twenty, or even just one of any given design. If you like what they're doing, you need to be on their mailing list, have about $80 stashed and ready to go, and be prepared to jump as soon as you get the message. Hats can sell out within minutes; those that don't can be found in the archives.

Here's their 48th drop as a sample; these fabrics are typical of what they use, but I especially liked the selection on display here. Their 49th includes a couple rare "cartoon character bedsheet" designs; you can guess which were the first to disappear. Funnily enough I'm not one to collect and wear really colorful caps myself, but I did get this nice denim cap with a suede brim that they still have two of left at the time of this writing.

They ship from New Zealand, but arrival in the USA is very speedy, and in an industrially-compostable plastic bag.
