What ON3P says about the Jeffrey 108
“The 2025 JEFFREY 108 is the most versatile all-mountain ATV in skiing – a 108mm hybrid freestyle twin engineered to balance lift and control, ready to drop anywhere.
Our classic SIGNATURE ROCKER (also available via Custom Builder) has all the trucking power you need, with an aggressive tip engagement zone that grips strong and rolls intuitively. A tight underfoot radius complements a wide shovel width, allowing for surprisingly solid carving while maintaining float, without unnecessary heft. Deceivingly agile for its width, and surprisingly beefy for its quickness, our flagship midfat is the definitive quiver killer – the only ski you’ll ever need.
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.”
