At swim meets, some swimmers pull on two caps. The setup is mainly used for racing, while one cap is common in everyday training.
Two caps are used in racing to hold the goggle strap between layers. For everyday training, one silicone swim cap is usually enough.
The real reason swimmers double cap
A common two-cap setup follows this order:
- First cap: latex, underneath. Latex is a common base layer; some swimmers use silicone for both layers.
- Goggle strap: in between. The goggles go on over the first cap, then the second cap goes on top. Keeping the strap between layers can help limit shifting during a dive or turn.
- Second cap: silicone, on top. Silicone is commonly used as the outer layer because it has a smooth, structured surface.
The practical reason is goggle security. A dive or flip turn can shift a strap, so some racers keep it between two caps. The setup also appears in triathlon and open-water racing.
Does a second cap make you faster?
A second cap may change how the outer surface sits, but this article does not establish a measurable speed benefit. The practical reason to double cap is goggle security.
Do not buy a second cap for a guaranteed time gain. Choose it for your racing setup and goggle preference.
Should you double cap for training?
Two caps can feel warmer, tighter, and more involved to put on and remove. Many swimmers save the setup for race day.
If a single cap slips in training, check fit, hair placement, and application first. We cover that in why swim caps slip and how to fix it.
Latex on the bottom or silicone? Does it matter?
Latex underneath and silicone on top is a common combination, but some swimmers use two silicone caps. Choose based on material preference and the setup allowed at your event. Our silicone vs latex vs lycra guide breaks down the trade-offs.
