FAQ

Quick answers about fit, care, shipping, returns, and silk.

Fit & Sizing

What size are the caps? Do they fit everyone?

Our caps are one size fits most, with an adjustable back strap so you can customise the fit. The structured crown and curved brim are designed to sit securely and comfortably.

Care

How do I care for my cap?

Spot clean with a soft cloth, cool water and a drop of mild non-bio detergent. Dab, don't rub. When it needs a proper clean, hand wash in cool water for under five minutes, with no soaking or wringing. Wipe the brass buckle dry, reshape while damp, fill the crown with a towel and air dry overnight, out of the sun. Wipe the silk sweatband after warm days. Never machine wash, tumble dry, bleach or iron the lining. Full care guide

Sero's Silk

Silk vs satin - what's the difference?

Many caps advertise a "satin" lining - that usually means polyester with a shiny finish. Satin is a weave, not a fibre.

Our interiors are 100% mulberry silk charmeuse at 19 momme: a natural protein fibre that is smoother against hair and helps reduce friction and breakage.

Cotton or polyester linings create more friction as the cap moves through the day. Silk is chosen specifically to help reduce friction and breakage.

Are Sero Silks caps lined with real silk and premium materials?

Yes, 100%

  • Lining & sweatband: 100% mulberry silk charmeuse (19 momme)

  • Exterior: 100% cotton twill

  • Hardware: solid brass buckle - no plastic
