And now, we’re here for you to guide you through the whole process of how to shrink a polyester cap to your head size without ruining the shape of your brand new cap or old, perfect example of its kind.

Can You Shrink a Polyester Hat?

When coming to polyester hats, the main quality of this synthetic fabric is that they have excellent stretchability properties and long-lasting durabilities. This makes the polyester cap more resistant to shrinkage and wrinkles when compared to caps made up of natural fabrics like cotton. So, you can make extra efforts to shrink your polyester cap without worrying about the risk of over shrinking.

However, the first and last thing to remember is, DO NOT throw in washing machines without a hat cage in hot temperatures to shrink your cap. Even though polyester is also heat resistant, hot water can damage the shape of the cap.

What to Know Before Shrinking a Polyester Hat?

1. Read the Care Label

First things first, do not avoid reading the care label on your caps for the only reason it’s tiny! Care labels give us a lot of information about the cap’s material and stay at its best, whether it needs hand washing or machine washing. The best part, it also tells you what you shouldn’t do with your cap, like NO TUMBLE DRY, NO MACHINE WASH, to not ruin the cap without knowing.

2. Check Color Bleed

If you’ve never washed your cap, don’t forget to check for color bleeds when using a water method. Most often, polyester caps are colorfast and don’t bleed much more than natural fabrics. But better safe than sorry! Use a white wet cloth to wipe the less prominent part of your cap. If it bleeds, avoid shrinking methods with water.

3. Shrink to the Right Size

If your shrinking process takes 15 minutes, take time to wear in between and feel the right fit of the cap. It’s necessary for a cap to be fitted but not overly tight. A tight-fitting cap has possibilities to reduce the blood flow within your scalp, cause frequent headaches and hair loss.

4. Use a Hat Cage

To be honest, washing machine machines are not better for your caps than hand washing since they might have chances to deform. But for shrinking your polyester caps, exposing them to hotter temperatures in the washing machine or dishwasher is a very effective method to shrink polyester caps. So how to protect the shape? Simple! Use a hat cage for your baseball cap before you throw them into washing machines.

Now let’s do a quick rundown of the 4 methods which can effectively shrink your polyester cap without ruining the shape!

Wear a plastic bag on top of your head, and try to wear it on your head. If it fits well, you can air them dry with the hat cage itself.
