Most hats should stay out of the dryer. Putting a hat in the dryer exposes it to heat and tumbling that can shrink a sweatband and warp a brim. We have made hats since 1972 at American Hat Makers, and the hats we see damaged most often went through a hot cycle.
So, can you put a hat in the dryer? Air dry your hat on a rounded form, and use a tumble dryer only when the care label clearly approves it. A machine-washable hat is not automatically dryer-safe. Both appliances stress materials differently, so the label must approve each method separately.
Mastering the basics of washing hats and drying them protects their shape. Consistent hat care and maintenance takes very little effort.
When drying hats, a towel, a rounded support, and a shady spot with good airflow will preserve the original fit. You can clean a hat safely without risking heat damage.
Key Takeaways
-
Air drying on a rounded form is the safest default for almost every hat.
-
A washable label and a dryer-safe label are two separate permissions.
-
Leather hats, straw hats, and structured felt hats need material-specific care and no dryer.
Why Heat and Tumbling Can Damage a Hat
Heat and tumbling attack the parts that give a hat its fit and shape. Warm air shrinks fibers and tightens sweatbands. The spinning drum crushes crowns and bends brims while the hat is soft and damp. The care label is the only thing that tells you whether a given hat was built to handle that.
How Heat and Agitation Affect Fit, Fabric, and Brim Shape
A hat is a small object with a lot of different parts packed into it. The crown fabric, the brim insert, the sweatband, the stitching, and any glue or trim all react to heat differently. When one part shrinks and another does not, the hat pulls out of shape.
Here is what we see most often after a dryer cycle:
-
Fit loss. Heat shrinks fabric and tightens the sweatband, so a cap that fit well can come out a size smaller.
-
Bent brims. Tumbling presses the brim against the drum while it is still damp, and it dries in that bent shape.
-
Loose trim. Glued patches, feathers, and hatbands soften in heat and can peel away.
-
Tired elastic. Elastic sweatbands and stretch fit systems lose their spring.
Many of our hats have a metal band sewn into the brim so you can reshape it. That feature makes the brim adjustable, but it does not make the hat dryer-safe. The same goes for packable styles such as our Crusher, Soaker, and Cabana. They are built to fold into a suitcase, which is a different stress from hot, spinning air. If you are also weighing the washing step, our guide on whether you can put a hat in the washer covers that question in detail.
What Does the Care Label Actually Allow?
The care label is your best guide, and it is more precise than many people think. In the US, the Federal Trade Commission requires a care label to state whether the product should be dried by machine or another method. So a label that says "Machine wash, dry flat" is telling you to keep the hat out of the dryer, even though it never says "Do not tumble dry."
Read the label this way:
|
Label wording |
What it means for drying |
|---|---|
|
"Tumble dry low" |
Dryer allowed on low heat only |
|
"Dry flat" or "Line dry" |
Air dry; skip the dryer |
|
"Spot clean only" |
Keep the hat from getting soaked at all |
|
"Dry clean only" |
Leave washing and drying to a professional |
|
No label |
Treat the hat as air-dry only |
Older caps, especially ones made before about 1983, often have no care label at all. When you cannot find a tag, assume the hat should air dry.
Which Hat Materials Need Extra Care?
All hat materials need some care, and the specific hat material and build matter just as much as the fiber tag. A cotton cap with a cardboard bill, a wool knit beanie, and a stiff felt fedora all call for different handling.
Cotton and Polyester: Fabric Content Is Only Part of the Answer
Both polyester hats and cotton hats are sturdy everyday options, but the tag does not tell the whole story. Even a pure cotton hat can shrink quickly with heat. Polyester and other synthetic fiber hats resist shrinking better, yet high heat can still warp trims and soften glued parts.
What decides dryer safety is the full build: the brim insert, the sweatband, the stitching, and any patches. A polyester bucket hat with a soft brim and nothing glued on is a very different hat from a structured polyester cap with a stiff front panel and a heat-pressed logo. Our Cabana sun hats, for example, are nylon and polyester, and we still recommend air drying them on a hat cone out of the sun.
Baseball Caps: Brim Inserts, Sweatbands, and Trims Matter
Baseball caps carry more hidden parts than most hats, and those parts fail first in a dryer. Newer caps usually have plastic brim inserts, which handle water better. Caps made before about 1983 often have cardboard bills that make a hollow sound when you tap them. Water and heat warp cardboard for good.
Before you clean a baseball cap, check four things: the brim type, the sweatband material, any glued or embroidered patches, and the fit system in the back. A plastic snapback strap can soften in heat. A leather strap can stiffen and crack. Fitted caps with no adjustment have no room to spare, so even small shrinkage changes how they sit.
Wool Beanies vs. Structured Felt Hats
Wool hats require thoughtful handling because natural fibers react quickly to agitation. An unstructured knit wool hat or beanie is stretchy, and some allow gentle hand washing in cool water. Heat and rubbing make wool felt hats and beanies mat and shrink, so skip the dryer entirely.
A structured felt hat is pressed and stiffened into a set crown and brim. Felt shrinks and loses its shape when soaked and tumbled, so it should never be fully wet or machine dried. To clean a felt hat, start with a soft hat brush and use a damp (not wet) cloth only on smudges.
Leather and Straw: Keep Them out of the Dryer
Straw hats and leather hats should never go in a washer or a dryer. Water and heat dry out leather hats, leaving spots and causing permanent cracking. Leather sweatbands also stiffen after soaking, while delicate suede styles should always stay dry.
Most straw is not waterproof. Soaking loosens the weave, and heat warps the brim. Our straw hats use materials such as Toquilla palm, Mexican palm, and woven straw, and all of them do best with dry brushing and very light spot cleaning. When you clean a straw hat, use cornstarch or talc on fresh sweat spots, then brush it away after a few hours.
How Should You Clean a Hat Before Drying It?
When washing hats, start with the gentlest method that works. The less water a hat absorbs, the less shape it has to recover. For most hats, routine hat care calls for brushing and spot cleaning, saving full immersion for washable fabric caps.
Start With Brushing and Material-Safe Spot Cleaning
Brushing is the first step for every hat. A soft-bristle brush lifts dust before it settles into the fibers. On felt, brush counterclockwise with the nap. On straw, brush along the weave. A small travel hat brush makes it easy to do this after dusty days.
Spot cleaning comes next. Dip a soft white cloth in cool water with a few drops of mild detergent, wring it out well, and dab only the dirty areas. Test a hidden spot first, such as under the brim, to check for color bleeding. Then wipe with a cloth rinsed in plain water. The sweatband holds most of the salt and oil, so it deserves the most attention; our steps to get sweat stains out of hats cover tougher yellowing.
When Is Hand Washing Appropriate?
Hand washing suits fabric caps and soft hats made from cotton, polyester, or nylon with plastic brims and colorfast dye. It gives you far more control than a machine.
-
Fill a clean sink with cool water and a few drops of mild detergent.
-
Let the hat soak for about 15 minutes.
-
Scrub the sweatband and dirty spots gently with a soft toothbrush.
-
Rinse in clean, cool water until no suds remain.
-
Press out water with a towel. Do not wring.
Skip hand washing for leather, suede, straw, structured felt, and cardboard-bill caps. If you want more detail on the process, our guide to wash a hat by hand covers stain prep and color testing.
Machine Washing Requires Explicit Care-Label Approval
Use a washing machine only when the care label allows machine washing. When machine washing hats, place the piece in a mesh laundry bag or hat cage. Use cold water, choose the gentle or delicate cycle, and add a small amount of mild liquid detergent.
A mesh laundry bag keeps straps from tangling around the agitator and protects structural stitching. Leave out bleach and fabric softener, and keep heavy items like jeans out of the load.
Machine washing approval says nothing about the dryer. When the cycle ends, take the hat out of the mesh laundry bag right away and move straight to air drying.
How Do You Air Dry a Hat Without Losing Its Shape?
When drying hats, air drying works best when you remove extra water and give the hat steady airflow without heat. A hat dries in whatever shape you leave it, so support the crown during the first ten minutes after cleaning.
Blot Excess Moisture Without Wringing or Twisting
Lay the hat on a dry towel, fold the towel over it, and press firmly. Repeat with a second dry towel if the first one gets soaked. Never wring or twist a hat. Twisting kinks the brim, breaks the stiffening in the crown, and leaves creases that stay after drying.
For spot-cleaned hats, blot the damp areas with a dry cloth right away so moisture does not spread into the surrounding fabric or straw.
Support Structured Crowns and Dry Knit Hats Flat
Structured hats need something round inside the crown while they dry. A hat form, a hat stand, an upside-down bowl, or a coffee can all work. You can also stuff the crown with a rolled hand towel. While the hat is still damp, push the crown back out and smooth or curve the brim the way you like it. If your brim has a sewn-in wire, set the shape now.
Keep the hat off its brim while drying, since resting on the brim flattens and warps it. Our Plastic Hat Stand sells for $8.00 and holds the crown up so the brim hangs free.
Knit beanies are the exception. Lay them flat on a dry towel, gently pat them back to their original size, and let them dry without hanging, since a wet knit stretches under its own weight.
Improve Airflow Without Adding Heat or Direct Sun
Dry hats indoors in a shaded room with good airflow. A fan on a cool setting speeds things up safely. Keep hats away from heaters, radiators, hair dryers, and hot car dashboards, since heat warps brims and dries out leather. Direct sun fades color, can yellow nylon, and dries out straw.
Most caps dry in about 24 hours. Wait until the sweatband is fully dry before wearing or storing the hat, because a damp hat shut in a closet can develop mildew. On rainy days, a rain and dust hat cover keeps water off in the first place.
When to Ask American Hat Makers About Reshaping or Refurbishment
If a hat loses its shape, shrinks, or gets damaged during cleaning, reach out before trying more home fixes. Our team can help you sort out whether reshaping, stretching, or refurbishment makes sense.
It helps to know how our coverage works. Our 50-Year Craftsmanship Guarantee covers defects in materials and workmanship, such as stitching coming undone or a band falling off. It does not cover damage from improper care or cleaning, including dryer damage. Refurbishment is a separate paid service. For hats without a prepaid Lifetime Refurbishment package, refurbishments start at $50 and vary with the style, materials, and work needed. Not every hat can be refurbished, so send photos and a detailed description of the problem to info@americanhatmakers.com, and we will let you know what is possible.
Protect Your Hat’s Fit With Gentle Cleaning and Air Drying
A hat keeps its fit longest when you clean it gently and let it dry on its own. When washing hats, check the care label first, and treat "machine wash" and "tumble dry" as two separate permissions. Brush every hat, spot clean what you can, and save hand or machine washing for fabric hats built for it.
Keep leather, suede, straw, and structured felt out of both the washer and the dryer.
After cleaning, blot without wringing, support the crown on a rounded form, lay knit beanies flat, and dry everything in a shaded spot with cool airflow. If you are unsure how to care for one of our hats, email us at info@americanhatmakers.com before you start, and we will help you pick the right method.
Frequently Asked Questions
Can I put a hat in the dryer on a no-heat setting?
An air-only setting removes the heat, but the tumbling can still crush the crown and bend the brim. We recommend it only for soft, unstructured fabric hats whose labels allow tumble drying. For anything with a stiff brim, sweatband, or trim, air dry on a form.
What is the fastest safe way to dry a hat?
Blot it firmly between dry towels, set it on a rounded form, and place it near a fan on a cool setting in a shaded room. Swapping a damp towel stuffed in the crown for a dry one after an hour also helps. Skip hair dryers and heaters, since heat warps brims and tightens sweatbands.
Can I put a bucket hat in the dryer?
Only if the care label says tumble drying is allowed, and then on low heat. Many bucket hats have stitched brims, interfacing, or trim that can pucker in heat. Air drying on an upside-down bowl keeps the brim even and is the safer choice.
Should I use the dryer to shrink a loose hat?
No, because dryer shrinking is uneven and you cannot control where it happens. The crown, brim, and sweatband shrink at different rates, which pulls the hat out of shape. A size reducer or sweatband liner behind the band tightens the fit without changing the hat itself.
Can a hat that shrank in the dryer be restored?
Sometimes, depending on the material and how much it shrank. Mild shrinkage in cotton, straw, or felt often responds when you stretch a hat with a hat stretcher, but warped brims or melted trim may not fully recover. For one of our hats, send photos and a description to info@americanhatmakers.com so we can tell you whether refurbishment is an option.
