Abstract: A sled construction consists of a generally concave sled which conforms to the buttocks of the sledder and a strap assembly for releasably securing the sled to the body of the sledder. A body portion of the concave sled includes an inner contoured surface which is received in conforming relation with the buttocks of a sledder and a outer surface having longitudinal runners extending downwardly therefrom. The sides of the body portion taper inwardly and curve upwardly to form symmetrical triangular wing portions which extend around the hips of the sledder. The front of the body portion tapers inwardly and curves upwardly to form an apex received adjacent to the crotch of the sledder. A substantially planar flange portion extends outwardly from the back of the body portion so that it is received adjacent a waist of the sledder. The body portion includes a lateral slot adjacent to the apex and the flange portion includes two symmetrically spaced slots therein.
