Questions, Answered.
A structured silicone swim cap with a moulded dome profile designed to create a clean, streamlined fit for racing and training.
Unlike a traditional flat silicone cap, the BEST Performance Dome Cap has a more structured shape that sits smoothly around the head and creates a sharper race-ready profile.
Both. It is built for competition but durable and comfortable enough for regular training sessions.
The cap should feel close and secure without causing excessive pressure. A firm fit helps reduce movement while swimming.
The flexible premium silicone can accommodate a range of hair lengths. Swimmers with longer hair should secure it tightly and evenly before putting the cap on.
No swim cap is designed to keep hair completely dry. Its primary purpose is to hold the hair securely, reduce movement and create a smoother profile through the water.
Yes. Some competitive swimmers wear a thin silicone cap underneath their dome cap to secure their hair and create a firmer race-day fit.
Hold the cap open with both hands, position the front edge near your forehead and carefully pull it backwards over your head. Avoid using fingernails, jewellery or sharp objects.
Rinse it with fresh water after each use and allow it to air dry away from direct sunlight and heat. Store it flat and keep it away from sharp objects.
