PERFORMANCEDome Cap

A structured swim cap made from flexible premium silicone, with a moulded dome profile for a streamlined fit.

PERFORMANCE is our standard close racing fit, with a secure internal grip designed to help hold the cap in position. PERFORMANCE+ has a larger dome and more internal room, for long or thick hair or swimmers who prefer a roomier fit. The + refers to the fit, not to higher performance.

Choose by head shape, head size and hair volume. The cap should feel close and secure without excessive pressure. Neither fit suits every swimmer. If you have long hair, tie it evenly before putting the cap on. Unsure? Contact our team before ordering.

Our core range is Abyss, Stealth and Arctic. The pastel range adds Cloud, Bubblegum, Honeycomb, Sage, Peach and Cherry, on the Pastel cap page. That is nine colours across our core and seasonal ranges. Availability varies by colour and fit, so select both to see what is currently available.

Both. The cap is designed for regular training and for racing. PERFORMANCE and lifespan depend on how it is used and cared for.

No. The cap is not designed to keep hair dry. It helps contain your hair and gives a streamlined profile in the water.

You can, but an extra cap changes how the fit and pressure feel. Choose the fit that is comfortable with whatever you wear underneath.

Hold the cap open with both hands and carefully pull it on from front to back. Avoid fingernails, jewellery and sharp objects, and do not overstretch it.

Rinse in fresh water after every use, air dry away from direct sunlight and heat, and store it dry, away from sharp objects. We cannot guarantee that colours will never fade.

For non-personalised retail caps, email support@bestswim.com.au within 30 days of delivery with your order number, and wait for return instructions before sending anything. The cap must be unused and unworn, never tried on or stretched over the head, clean, undamaged, in saleable condition and in its original packaging. Opening the packaging to inspect it does not on its own make it ineligible. You pay return postage for change-of-mind returns, and original shipping is not refunded. See our Returns & Refunds and Swim Cap Hygiene policies.

Email support@bestswim.com.au with your order number, a description and photos if available. We will provide the appropriate remedy under the Australian Consumer Law. For a major failure you can choose a refund or replacement; for other failures, repair, replacement or refund rights apply as relevant. Your rights to compensation for reasonably foreseeable loss or damage are preserved. The 30-day change-of-mind limit and the hygiene and packaging requirements do not restrict these claims, and we cover the required return postage.
