These are the best selling swim caps on Amazon, for several reasons. Firstly the colour range is unusual, striking and vibrant. The caps are made of a soft, stretchy material (spandex), which makes them easy to fit - and they don't pull hair as they are being put on. Most parents think this is bliss, and is well worth the minor drawback - they are not waterproof. We don't know of any child who has been put off swimming because their hair got wet, but we know of plenty who hate swimming because it hurts to put on their swim cap.
