By using Tyr's Tripwire technology, the Aqua Shift Cap shifts and harnesses the energy to your advantage at the first point-of-entry, making the benefits from Aqua Shift work instantaneously.

Your head is the leading edge of resistance. A strategically placed Tripwire on the patent-pending cap, along with a smooth rounded top, breaks, refracts and catapults you through the water, giving you the head start you've always been searching for.

Classic Size: Larger size fits adults and children.
