Have you ever felt a desire to doom all the inhabitants of the Earth? Are you convinced the Armada's coming to crush mankind? Is the phrase 'PITIFUL HUMAN' part of your everyday vocabulary? Then this might be the cap for you!

Inspired by the cult classic cartoon Invader ZIM, in honor of InvaderCON, this Irken fleece hat is the perfect choice for any Invader ZIM fan (or member of a conquering intergalactic army.) Designed by Saeru and crafted by hand, these caps are a fun and quirky addition to anyone’s winter wardrobe, or to wear around a convention.

Our Irken cap is made from soft, lightweight and durable fleece, ensuring your head will be warm and comfy on all your planet-crushing missions. The antennae are supported by lightweight foam cones, which can be easily removed and reinserted if you ever need to clean it. Our Irken cap is machine washable, but make sure to turn it inside out and line dry it to keep it looking its best.


We will make you your custom Irken in your color choices.

♦ Color & Shape Options:
- For the skin color = choose either APPLE (which is soft textured anti-pill fleece) or MELON (which is crisp smooth blizzard fleece)
- For the eye color = pick any of the options shown in the color comparison photo.
- For the eye shape = shown in the last comparison photo are the normal oval-shape on top, the Tallest-style rectangles in the middle and the squinting version on the bottom.

(Shown in the first 3 photos are examples of the most classic color scheme = Ruby and Amethyst eyes on Apple skin.)

♦ Sizing:
By default, your cap will be a MEDIUM SIZE (about 23”-24” circumference) which will fit most adults. If needed, they are also available in LARGE (about 25”-26”) or SMALL (about 21”-22”) as well.


♦ CARE ♦

To clean, we recommend hand-washing in cool water with mild detergent after removing the foam cone inside the antenna. You may machine-wash as well - just turn the hat inside out and/or wash inside a pillowcase. Please air-dry to keep it looking new. Any wrinkles caused by transport/storage should work themselves out simply by wearing for a bit -or- may be taken care of with an iron on a low-setting.



Note: This hat is made to order. Please allow (up to) 2 weeks before being shipped out to you.

- DOMESTIC = after completed, hat will be delivered generally within 2-3 days from then. Online tracking is included.
- INTERNATIONAL = after completed, will ship out within a week by first class airmail (delivery/customs time varies by country.) Online tracking is not included by default, but can be added on *prior* to check-out if a different shipping option is requested.

If you require Priority Mail or Express Mail, you *must* e-mail us at "" prior to checking out so we can adjust the listing for you. (We can't edit orders after you check out and pay.)

Hat will be shipped folded in an over-sized envelope.
