Quick answer

Clean your CP01 Cap by hand in cool water with a mild detergent, focusing on the sweatband and front panels. Never machine wash or tumble dry it. Air-dry the cap on a round object or cap form so the curved brim and crown hold their shape, then store it somewhere it will not be crushed.

Why cotton twill caps need a gentler routine

The CP01 Cap is made from 100% cotton twill with embroidered logos at the front and back. Cotton twill is durable, but it is also a woven fabric that can shrink, soften, or distort when exposed to heat and agitation. Embroidered logos add another layer of care: harsh scrubbing or hot water can fray the stitching or dull the thread.

That is why the routine below avoids the washing machine and the dryer entirely. Hand washing gives you control over where the water and detergent go, which matters most around the sweatband and the front panel where oils and sweat collect.

Spot-treat sweat stains before they set

Sweat stains on a cap usually show up along the inner band and sometimes on the front panel where the brim meets the crown. The longer they sit, the more they bond with the cotton fibers. Treat them as soon as you notice discoloration or a lingering smell.

Mix a small amount of mild liquid detergent with cool water. Dip a soft cloth or soft-bristled brush into the solution and work it gently into the stain using small circular motions. Avoid rubbing hard enough to stretch the twill or disturb the embroidery. Let it sit for a few minutes, then rinse the area with a clean, damp cloth.

Hand wash the whole cap when spot treatment is not enough

Fill a basin with cool water and a teaspoon of mild detergent. Submerge the cap and let it soak for about ten minutes. Gently squeeze the suds through the fabric with your hands, paying extra attention to the sweatband and the inside of the crown.

Do not wring or twist the cap. Rinse it under cool running water until no suds remain. If the water runs clear, you have rinsed enough. A common mistake is using hot water to speed up the process; hot water is one of the fastest ways to shrink cotton and warp a curved brim.

Dry the cap so the brim and crown hold their shape

After rinsing, gently press the cap between two clean towels to remove excess water. Do not twist or wring it. Then place the cap over a round object that matches the inside of the crown, such as a cap form, a clean bowl, or a rolled towel. This supports the fabric as it dries and helps the curved brim keep its shape.

Air-dry at room temperature, away from direct sunlight and radiators. Never put a cotton twill cap in a tumble dryer. The heat and tumbling action can shrink the crown, soften the brim, and distort the embroidered logos.

Store your cap so it stays ready to wear

Once the cap is completely dry, store it in a spot where it will not be crushed. Hanging it on a hook or a cap rack keeps the crown open. If you stack caps, place them so the brims are not bent under weight.

For long-term storage, keep the cap away from damp areas and direct sun. A dust bag or a breathable cotton pillowcase works well if you want to protect it from dust without trapping moisture.

Step-by-step CP01 Cap care

  1. 1. Check the cap and close the Velcro: Look over the cap for loose threads or heavy stains. Fasten the Velcro strap so the hook side does not catch on the twill or embroidery during cleaning. Checkpoint: the Velcro is closed and the cap is free of loose debris.
  2. 2. Spot-treat sweat stains with cool water and mild detergent: Mix a drop of mild liquid detergent with cool water. Use a soft cloth or soft brush to gently work the solution into the sweatband and any stained areas on the front panel. Common mistake: scrubbing hard enough to stretch the twill or fuzz the embroidery.
  3. 3. Hand wash in cool water: Fill a basin with cool water and a teaspoon of mild detergent. Soak the cap for about ten minutes, then gently squeeze suds through the fabric with your hands. Rinse under cool running water until no suds remain. Checkpoint: rinse water runs clear and the cap is not twisted or wrung.
  4. 4. Press out excess water with towels: Lay the cap between two clean towels and press down to absorb water. Do not wring, twist, or roll the cap to force water out. Common mistake: twisting the brim, which can bend the curve out of shape.
  5. 5. Air-dry over a round form: Place the cap over a cap form, clean bowl, or rolled towel that supports the crown. Let it air-dry at room temperature, away from direct sun and heat sources. Checkpoint: the cap is fully dry before you wear or store it.
  6. 6. Store it where it will not be crushed: Hang the cap on a hook or cap rack, or place it in a breathable bag. Avoid stacking heavy items on top of the crown or brim. Next step: rotate your caps so each one rests in shape between wears.

CP01 Cap details that affect care

  • CP01 Cap: 100% cotton twill with embroidered logos at the front and back, curved brim, embroidered eyelets at crown, and Velcro fastening. Cotton twill responds well to cool hand washing but can shrink or distort with heat, so avoid hot water and machine drying. The embroidered eyelets and logos need gentle handling to stay intact, and the Velcro fastening should be closed before washing to prevent it snagging the fabric.
