Free history lesson: “J” skis is owned and operated by Jason Levinthal, founder of Line Skis. In 2013, Levinthal founded his new brand. His mission was to rely on 20 years of ski building experience to produce small quantities of limited-edition skis and sell factory direct to you. Lesson complete. Among J’s recent offerings is the Allplay, and it’s exactly that. Testers unanimously celebrated its playfulness. “Plenty of play for the park,” said one. “Great pop … and still ultra-stable and had great edge grip when nuking,” chimed another. Carbon stringers provide that lightweight maple core and four-way fiberglass contribute top-notch energy transfer and responsiveness. Well done, J.
