ON3P Jeffrey 108 — In‑Depth Review

Overview

The ON3P Jeffrey 108 blends playful twin‑tip freestyle DNA with real all‑mountain composure. At 108 mm underfoot with ON3P’s Signature Rocker, it pivots and floats easily in soft snow yet remains calm and supportive when you push the speed. If you like side‑hits, switch takeoffs/landings, and a loose‑but‑confident feel across varied conditions, this is a standout.

Who it’s for

Advanced to expert skiers with a playful or freestyle‑leaning style.
Riders in snowier regions who want one ski for pow days, chop, trees, and daily laps.
Anyone who values durability and damping over ultralight weight.

Construction and specs (and what they mean)

Rocker profile: Signature Rocker — rockered tip/tail with camber underfoot. Shorter effective edge boosts agility and float, while camber retains grip and pop.
Width: 135–139 mm tip / 108 mm waist / 129–132 mm tail (by length). At 108 mm, it’s a versatile width for soft snow and a one‑ski quiver in snowy areas.
Sidecut radius: ~19–22 m (grows with length). Encourages medium‑to‑long turns, stability at speed, and easy slarves over ultra‑tight carving.
Weight per ski: ~1.83–2.26 kg. On the heavier side for better damping, stability, and longevity; less ideal for long tours.
Core/laminates: 100% bamboo + fiberglass/carbon. Lively yet strong, with torsional support for dependable edge hold.
Base/edges: Thick Durasurf 4001 base and 2.5×2.5 mm steel edges. Standout durability for rails, rocks, and many seasons.
Full twin tip: Aids switch performance, butters, and playful moves.

On‑snow performance

Powder & soft snow: High tips and twin rocker keep the Jeffrey 108 planing and maneuverable in trees and steeps. It feels surfy yet predictable on landings.
Chop & crud: Extra mass and bamboo damping smooth out impacts; it slashes and pivots without getting twitchy.
Groomers & hardpack: Solid edge hold for everyday groomers. The medium radius prefers medium‑long turns; on true ice it’s competent but not a race carver.
Park & switch: Progressive mount and full twin make butters and switch approaches intuitive. Landings feel secure thanks to the platform and heft.

Mounting and sizing

Mount point: The recommended (progressive) line suits freestyle/all‑mountain use. More directional skiers may prefer −1 to −2 cm for extra tip drive and stronger tail support.
Size choice: Pick your height or size up if you ski fast, want stability, and see a lot of soft/chopped snow. Size down if you’re park‑focused, in tight trees, or lighter weight.

Comparisons

Armada ARV 106: Lighter and looser, but less damping and long‑term durability than the Jeffrey 108. ON3P feels calmer in chop.
K2 Reckoner 112: Softer and surfier; Jeffrey 108 is more precise on edge and steadier at speed.
Moment Wildcat 108: More directional and chargy; Jeffrey 108 is more freestyle‑friendly and easier to pivot.
Blizzard Rustler 10: Better hard‑snow carving and directional feel; Jeffrey 108 offers more switch/park capability and a looser ride.

Potential drawbacks

Weight: Great for damping, not for big touring missions.
Ice performance: Adequate, but not a specialist carver on boilerplate.
Progressive stance: Directional skiers may need a brief adjustment or a small mount setback.

Key takeaways

Playful all‑mountain twin‑tip: Surfy feel with true stability in chop.
Built to last: Thick base/edges and bamboo core deliver standout durability.
Medium radius: Natural in medium‑long turns and slashes; not a short‑turn carver.
