A drag-inducing mat includes a main body configured to accommodate a rider. The main body includes a rider surface configured to face the rider and an opposing surface configured to face a slide surface. The drag-inducing mat also includes a sipe array defined within the opposing surface. The sipe array includes a plurality of sipes that extends from a first lateral edge of the main body to a second lateral edge of the main body to selectively induce friction between the main body and the slide surface based on force applied to the sipe array by the rider.
