100 mm Freeride Alpine Ski
Dynastar M-Free 100 Alpine Ski
Skiers hunting one resort ski for soft snow in the morning and firm groomers by afternoon are the reason the Dynastar M-Free 100 Alpine Ski exists. A 130-100-122 mm shape at 178 cm floats well enough to make a storm day worthwhile while the 17 m radius at that same length keeps the ski quick in trees, and Adaptiv Sidecut blends the underfoot turn shape into the tip and tail so pressure builds through the arc rather than grabbing at the shovel. At 1,800 g per ski in a 178, on a Hybrid Core 2.0 that runs poplar wood fiber in three directions against a polyurethane sidewall frame, the M-Free 100 suits daily resort laps, side hits and soft-snow days.

Is This the Right Ski for You?
Best For
Advanced resort skiers who want one playful ski for storm days and groomers, ski 95 to 105 mm underfoot, and would rather have pop and pivot than the damping of a metal laminate.
Consider Another Ski If
You ski mostly firm snow and want a narrower carver, you need a dedicated powder ski above 110 mm, or you want metal underfoot for high-speed stability in crud.

Why We Like It
- The sidecut widens with length, from 129-99-121 mm at 162 and 170 cm to 131-101-123 mm at 185 cm, so a long M-Free 100 floats better rather than just running longer.
- Radius climbs from 13 m at 162 cm to 18 m at 185 cm, which is a wide enough spread that length choice genuinely changes how the ski turns.
- Hybrid Core 2.0 mills poplar wood fiber in three directions and frames it in polyurethane along the sidewalls, and that is what keeps a 100 mm ski at 1,800 g per ski feeling energetic rather than heavy.
- Full sidewall construction runs the vertical sidewall from tip to tail, which is what lets a rockered 100 mm freeride ski still hold a clean edge on morning corduroy.
Best Uses
- Storm days and soft snow inside the resort
- Daily resort laps across mixed snow
- Side hits, natural features and switch landings
- Trees and bumps at shorter lengths, open terrain at 185 cm
- Alpine and GripWalk bindings on a flat mount
Ski Selection Advice
Length changes this ski more than it changes most. Radius runs 13 m at 162 cm, 15 m at 170 cm, 17 m at 178 cm and 18 m at 185 cm, and the shape widens over the same span from 129-99-121 mm to 131-101-123 mm, so a 170 is a quick tree ski and a 185 is an open-terrain ski that floats better. Weight tracks length too, from 1,650 g per ski at 162 cm to 1,850 g per ski at 185 cm. Skiers who ride switch or spend time on features often size down one length; skiers who point it should not.
The M-Free 100 is a flat ski that takes a standard mount at the factory line marked on the ski, and full sidewall construction holds screws without a reinforcing plate. Choose a brake that clears 100 mm underfoot, so a 100 or 110 mm brake, and match the binding to your boot sole norm rather than to the ski. Skiers who want to use this ski for occasional touring should note it is a resort ski at 1,800 g per ski and there is no tech fitting or skin notch.

Compare the Dynastar M-Free 100
M-Free 100 vs. Dynastar M-Free 94
The Dynastar M-Free 94 is the same construction 6 mm narrower, at 1,700 g per ski in a 179 against 1,800 g in a 178. Skiers who see more soft snow than corduroy take the M-Free 100; skiers who want quicker edge changes on hard snow take the M-Free 94.

M-Free 100 vs. Atomic Bent 100
Both sit at 100 mm underfoot with no metal and a playful brief. The Atomic Bent 100 skis looser and more surfy underfoot, while the Dynastar M-Free 100 carries a 130 mm shovel and full sidewall for a firmer edge on hard snow. Skiers who slash choose the Bent 100; skiers who carve between slashes choose the M-Free 100.

M-Free 100 vs. Blizzard Rustler 10
The Blizzard Rustler 10 is 102 mm underfoot with a titanal laminate through the tip and tail, so it stays calmer at speed in cut-up snow. The Dynastar M-Free 100 has no metal and swings lighter for features and switch skiing. This is a damping against pop decision.

Common Questions
Who should buy the Dynastar M-Free 100?
The Dynastar M-Free 100 suits advanced resort skiers who want one ski for storm days and groomers and who ski creatively rather than only fast. At 100 mm underfoot with a 130-100-122 mm shape and a 17 m radius at 178 cm, the ski floats soft snow and still comes around quickly in trees, and the metal-free poplar and polyurethane core keeps it energetic underfoot.
What bindings work with the Dynastar M-Free 100?
The Dynastar M-Free 100 is a flat alpine ski, so it accepts any alpine binding on a standard mount and needs no reinforcing plate under full sidewall construction. A ski does not set boot compatibility, so match the binding to your boot sole norm, whether ISO 5355 (Alpine), ISO 23223 (GripWalk) or a multi-norm binding. Use a brake that clears the 100 mm waist, so 100 or 110 mm.
Is the 1,800 g weight per ski or per pair?
Per ski, at 178 cm. Dynastar labels the weight column in its own spec tables as kilograms per pair, but the product copy on the same range quotes the identical figures per ski, and a 100 mm full-sidewall ski at 900 g per ski does not exist. We publish per ski at every length: 1,650 g at 162 cm, 1,700 g at 170 cm, 1,800 g at 178 cm and 1,850 g at 185 cm.
What is the turning radius of the Dynastar M-Free 100?
The Dynastar M-Free 100 runs a 13 m radius at 162 cm, 15 m at 170 cm, 17 m at 178 cm and 18 m at 185 cm. The sidecut also widens across the size run, from 129-99-121 mm at 162 and 170 cm to 131-101-123 mm at 185 cm, so the radius change comes from shape as well as length.
Does the Dynastar M-Free 100 have metal in it?
No. The Dynastar M-Free 100 uses Hybrid Core 2.0, a poplar wood core milled in three directions with a polyurethane sidewall frame, reinforced with unidirectional fiberglass and no metal laminate. That keeps the ski light for its width and lively out of a turn. It also means a metal-reinforced ski of the same waist will feel calmer in chopped snow at high speed.
Can the Dynastar M-Free 100 be used for touring?
It can be skinned on a hybrid binding, but the Dynastar M-Free 100 is a resort ski and it is honest to treat it that way. At 1,800 g per ski in a 178 it is heavier than a purpose-built touring ski of the same width, and there is no skin notch or tail clip tab, so a strap-and-clip skin is the practical answer. Skiers who tour regularly are better served by a touring construction.
Our Verdict
The Dynastar M-Free 100 Alpine Ski is a strong pick for skiers who want a resort ski that treats a storm day and a groomer with equal interest. The shape widens across the size run from 129-99-121 mm to 131-101-123 mm and the radius runs 13 m at 162 cm to 18 m at 185 cm, so length choice actually shapes the ski you get, and Hybrid Core 2.0 with three-direction poplar wood and a polyurethane sidewall frame keeps it energetic without metal. At 1,800 g per ski in a 178 the M-Free 100 gives up some high-speed calm to a metal-reinforced ski and gets back pop, pivot and a lighter swing weight, which is the right trade for skiers who ski the mountain as terrain rather than as a racecourse.
