The Manta Paddles are designed to increase strength, stroke efficiency, and distance per stroke. Constructed with the same lightweight, durable, floating material as our Agility Paddles, these paddles are comfortable to wear and won't get lost underwater. The strapless design fits the natural contour of your hand and teaches you to apply even pressure throughout your pull. The curve of the paddle allows you to reach full extension while gently forcing your hand into the catch of your stroke. Vent holes allow for water to pass smoothly through the paddle, letting the swimmer maintain a good feel for the water.
