Fit tips

  • Between two sizes? Take the larger one. Cotton caps stretch gently and your child grows into it.
  • Caps with ties adjust a little under the chin.
  • Knitted caps are naturally stretchy. Choose your exact size for a snug, warm fit.

Wrong size? No problem.

You can exchange your cap for a different size. Just let us know within 7 days of delivery. The cap must be unworn, unwashed and have its original tags attached. Postage for the exchange is paid by the customer. See Shipping & Returns for details.
