What ON3P says about the Jeffrey 100
“The 2025 JEFFREY 100 is the most adaptable all-mountain airframe in skiing - a 100mm twin engineered to balance lift and control, ready to drop anywhere.
Our classic SIGNATURE ROCKER (also available via Custom Builder) has all the jetpower you crave, with an aggressive tip engagement zone that grips strong and corners tight. A compact underfoot radius compliments a wide shovel width, allowing for hard carving while maintaining float, in a utilitarian width that can serve skiers from both coasts. The Jeffrey 100 crushes hardpack, pow, park, crud, and anywhere between - our most versatile option for freestyle pilots needing a quiver of one.
The Jeffrey shape series maintains the all-mountain focus and freestyle DNA our trademark silhouette has always been known for. Featuring our custom 2800 hybrid fiberglass/carbon composite, the Jeffrey balances a medium weight with noted strength and durability. Combined with our 100% bamboo cores, full length UHMW sidewalls, and the thickest bases & edges money can buy, the Jeffrey is the standard for fun, stable, and playful freestyle skis that can take a beating.”
