Bubble swim cap
Latex swim cap with chin strap. Available in purple, white and blue. To determine which size is best for you, measure the circumference of your head, slightly above your ears.
- Small 20 1/2 to 21 5/8 inches
- Medium 22 to 22 3/8 inches
- Large 22 3/4 to 23 1/8 inches
The cap will stretch and form to your head's size. If you have long or thick hair, consider going one size larger than you would normally measure. And if you have thin or short hair, you might be best going one size down.
