It may seem like an oxymoron, but the Jr. Vortex Combos are the compact version of the "Big Daddy" adult Vortex combos. These skies are perfect for getting pre-teen to early teenage skiers up and out of the water and skiing like legends! They work great for lighter adults, too. The 54" Jr. Vortex offers the extra surface area that works so well on the adult Vortex, but in a smaller, more maneuverable size for younger and lighter skiers.
