Swim caps on this page cost between $5.99 and $45. Common materials are silicone, lycra and elastomeric blends, offered in solid colors and a few patterned options.

Silicone caps provide a tight seal and reduce drag, while lycra caps are softer and easier to pull on; consider the thickness if you need extra hair protection.

Check that the cap fits snugly without gaps, and pick a style that stays in place during flips or long swims.
