The Dynastar M-Free 90 Skis are an awesome all-mountain ski for younger skiers who have outgrown the JR skis, or lighter adult skiers wanting a more poppy and playful ride that can still carve well. Dynastar uses a Paulownia wood to keep the M-Free light and super responsive and pairs it with a twin-tip design to allow for a loose and playful feel underfoot as well. These skis are impressive, in that I can carve effectively on firm snow with them, but also slash and pivot my way through tighter terrain and softer snow too. These skis also easily do double time in the park as well for more creative riders. They do have a softer flex than the wider M-Frees, so heavier and more aggressive skiers should look to those. But for skiers wanting a super expressive ski and don't need an overly stiff ski, the M-Free 90 is a great value ski: high bang for the buck!
