Zoggs Centre Line Snorkel is a handy swim training aid which allows you to focus on perfecting your stroke without the need to turn your head to breathe. Using a swim snorkel enables you to concentrate on your body position in the water as you don't have to turn your head to breathe. You will be able to align your head and spine and hold the lower part of your body higher in the water. By not having to look away to breathe, you are able to watch your hand position as it enters the water and correct if necessary. The adjustable head bracket is designed to not interfere with your goggles, providing a secure fit and reinforced split yoke strap for comfort. The snorkel comes with a nose clip and angled Vylux mouthpiece for superb comfort and encouraging a focus on stroke rather than turning for the next breath.
